Industry News TalkTalk presses ahead with dark fibre plans after winning appeal on BT costs

TalkTalk are preparing to launch business broadband products from October after successfully arguing Ofcom’s method for determining dark fibre access caps were miscalculated.

Dark fibre is to be offered to TalkTalk customers using Openreach infrastructure after the Competition and Markets Authority (CMA) upheld its appeal over the extent of BT access charges. Previously, Ofcom had ordered BT to provide third party communications providers with access to Openreach’s dark fibre as part of the Business Connectivity Market Review (BCMR). The review had also proposed fibre and legacy business broadband connection price controls plus new obligations for Openreach that they were to speed up the installation and repair leased lines. As it stands, Openreach makes leased lines used by public sector organisations and businesses, available to other companies on a wholesale basis. This means that the line and equipment used to power the connection are bundled together. In the £2 billion market for leased lines Ofcom claims the measures should result in better services, lower prices and more effective competition. However TalkTalk felt that the methodology used to calculate the wholesale price caps was flawed as it did not take into account government rate rules. In its ruling the CMA agreed and Ofcom must therefore recalculate. BT has its own appeal which is still yet to be ruled on and still feels Ofcom’s decision is disproportionate. In a separate appeal CityFibre’s complaint on Ofcom’s choice of cost standard was thrown out by the CMA.

No superfast broadband requirement in Digital Economy Bill The Digital Economy Bill has received a last-gasp Royal Assent in the run up to the UK general election in June, but an amendment sought by the House of Lords insisting on a legal minimum broadband speed of 30Mb/s has been dropped. It was felt that not enough people have taken up a superfast broadband in order to warrant it.

The 30Mb/s amendment was initially proposed by Labour’s Lord Mendelsohn in February, increasing on the initial 10Mb/s universal service obligation (USO). While providing a universal 30Mb/s service could cost as much as £800m more, Mendelsohn argued that the economic case for it was “extraordinarily well justified”. However, Digital and Culture Secretary, Matt Hancock, said he had serious concerns as to whether the amendment was deliverable, and felt it counterproductive to set a 30Mb/s USO because of the risk of legal challenges by network builders, and the delays that would cause. The government is therefore to propose a further amendment in lieu requiring a broadband USO to be set at 10Mb/s, and for this to be reviewed by a future government once take-up of superfast broadband services hits 75%, whenever that might be.

In Brief Interxion to Expand London Campus

Interxion have announced that it is to expand its London Data Centre Campus. Scheduled to open in 2018, LON3 will add 1,800sqm to its uniquely located central London data centre campus, situated between the Square Mile and Tech City. The campus has become a strategic location for businesses looking to interconnect mission critical services in central London. Home to key players in the financial services, digital media, connectivity and cloud services sectors, Interxion plays an important role in enabling London’s digital economy.

New reports predict Telco Cloud to Reach Critical Mass After 2020, fuelled by 5G Large scale telco cloud deployments will hit global critical mass after 2020 in parallel with the deployment of 5G, according to a new report from ABI Research.The report, titled ‘Telco Cloud Framework and Deployment Roadmaps’, argues the latest network generation will likely require a new core network to allow for advanced concepts, including network slicing and niche services. Early 5G deployments, during which time there will not be an immediate need for a new telco core, will likely focus on enhanced mobile broadband.

Another report from GSMA predicts that the commercial 5G networks will be widely deployed at the beginning of the next decade and, by 2025, will provide coverage to a third of the world’s population.

What they’re saying As we report in LINX News on page 6, it has been announced that LINX has selected Ciena as a partner on its new data centre interconnect Waveserver platform. Ciena’s Keri Gilder and LINX’s Richard Petrie tell us more.

“The services LINX offers play a huge role in today’s interconnected, on-demand era”

Keri Gilder, Vice President and General Manager, EMEA, Ciena “Today’s economies, governments and educational institutions depend on global connectivity for everything from collaboration to entertainment to political action, and that would not be possible without organisations like the London Internet Exchange. The services LINX offers play a huge role in today’s interconnected, on-demand era, and Waveserver provides the underpinning network, using significantly less space and power, to cost effectively service its customers and rapidly scale so that all users benefit.”

Geo TLDs of cities and regions give websites a local foothold In 2012 ICANN, the Internet Corporation for Assigned Names and Numbers, decided that the entire system of domain extensions had to be thrown open. In addition to conventional generic extensions (.com, .org, .biz, etc.), and the two-letter country extensions (.be for Belgium, .nl for the Netherlands, etc.), a whole range of new domain extensions would be created with “ordinary” or generic terms. The introduction of these new generic Top Level Domains or gTLDs is a process that gradually picked up steam and reached cruising speed last year. Today, there are 1,213 new TLDs to choose from, and more than 27.5 million domain names have been registered with one of these extensions. They consist of a wide array of terms, ranging from marketing-sensitive words (.fan, .guru, .top...), professions (.lawyer, .architect, .immo...) to health (.health, .dentist, .doctor) and food & drink (.menu, .pizza, .restaurant...).

Richard Petrie, LINX Chief Technical Officer “We’ve built a strong relationship with Ciena very quickly after successful proof-of-concept testing last year. The company has been very supportive of our project time frames and clearly understands the IXP market. Additionally, Ciena is keen to engage with the LINX membership and as capacity grows we can see many benefits for all parties.”

Other geoTLDs have been set up to bring together larger groups of countries such as .africa for African countries or .lat for Latin America. And finally, there are city TLDs such as .amsterdam, .gent (Ghent), .berlin, etc.

The new geographic domain extensions provide an answer to the wish of companies and organisations to underscore their local foothold in their city or region.

New Top Level Domains (TLDs)

“Ciena is keen to engage with the LINX membership”

Geographic TLDs

Geographic, or geoTLDs, constitute a separate group in these new extensions. They often have to do with regions which were left out of the country code TLDs, because they are not an independent country, although they are a clearly distinguishable region within that country, with their own identity, culture and language. DNS Belgium’s own .vlaanderen and .brussels TLDs which up to now fell under .be (Belgium) come immediately to mind, but also .scot (Scotland) and .wales (Wales) within .uk (United Kingdom). Other areas include .quebec which distinguishes itself from the rest of Canada (.ca) by having French as the main language, .bzh (Brittany), with its own language, just like .corsica falls under France (.fr) and .krd for Kurdistan. All these regions have their own identity and culture in the digital world thanks to these domain extensions.

Some Figures Although the geographic TLDs are by definition geared to a smaller group than more general terms such as .cloud or .party, they are very successful nonetheless. They seem to meet the needs of companies and organisations to stress their local foothold. In the top 100 gTLDs with the largest number of registered domains, .kiwi (New Zealand) is the first geo TLD you will come across (202,000 registrations – 27th place). The Big Apple (.nyc) follows at 41st with 73,836 registrations, and Berlin is 49th with 58,733 registrations. Other city TLDs that are extremely successful include .amsterdam (25,800), .london (57,300) and .paris (22,000). For more statistics on the popularity of the nTLDs, go to HotLINX would like to thank LINX associate member, DNS Belgium, who kindly provided the TLD information and data for this article.

In a new development all candidates have been interviewed in advance with questions put to them via the membership. Their responses have been recorded and available for members on the LINX website:

In previous years election votes were often submitted in advance well before the AGM so these ‘virtual hustings’ allow voters more time to make an informed judgement on the candidates. Formal details of the candidates, and other matters to be dealt with at the AGM, have been circulated to the LINX membership. All members’ main corporate representatives should now have received printed and emailed voting packs.

Voting at the AGM

The LINX AGM will be administered by Electoral Reform Services, part of the Electoral Reform Society. Members may vote on the resolutions, as well as in the Board election, in person during the meeting, online prior to the meeting, or by submitting a written proxy form by post. Members can also take part in the AGM remotely by secure webcast, requiring member authentication: If you have any questions on the AGM, please contact the LINX Member Relations team at


LINX selects Ciena’s Waveserver platform for datacentre interconnect services

It has been announced that LINX has teamed up with Ciena, a network strategy and technology company, to deploy their Waveserver product. Waveserver is a stackable datacentre interconnect (DCI) platform, which will be used to connect LINX’s datacentres throughout London and improve peering services for members. The Waveserver enables LINX to support the growing traffic demands of members by quickly, reliably, and more economically turning up larger and multiple low-latency connections to its data centres. Ciena’s Waveserver means that LINX can provide multiple terabits of connectivity between its sites in Harbour Exchange in Docklands, Equinix LD5 in Slough and Interxion locations in the centre of London. The platform has 400Gb/s of line capacity plus any mix of 10G, 40G or 100G of client Ethernet services up to 400Gb/s, in a compact, one rack unit form factor. Ciena’s Waveserver platform has the flexibility to allow LINX to design and build unique and customisable applications to evolve services based on member needs. In addition, LINX utilised Ciena’s Emulation Cloud product, an open application development environment, that allowed the LINX Technology team to create and test new applications and also prepare for the deployment before the equipment was delivered.

Are you considering connecting at 100G? Help us to plan capacity by letting us know

If you are considering connecting at 100G it would help us if you could share your plans in advance to enable us to deliver your port requirements as swiftly as possible. To let us know, or to obtain further information on 100G, please email the Member Relations team:

Engineering Update Capacity Upgrades, Route Servers and Network Automation By Mike Hellers, LINX Network Engineering Manager

Capacity upgrades in Slough

The project to increase capacity to our LON1 site at Equinix in Slough has now been completed. The site now consists of two MX960 based Edge routers. One of them is a high-density edge router, only MPC7 line cards in 40G mode for the ISL links to the rest of the network, and in 4x100G mode to connect member facing ports. The router is connected a 2x 960Gbps to the core sites in Interxion and Harbour Exchange. The optical transport capacity to Slough is provided through our new DCI platform based on Ciena Waveserver equipment. The existing Edge router will be used to continue to deliver 10G and 1G member ports.

JUNOS and Routing Engine upgrades

We are also continuing our project to upgrade all Juniper MX based routers to Junos 15.1 and new Routing Engines. The upgrade to 15.1 brings a number of fixes and improvements to our network. These include significant improvements on the reliability of IPFIX data which is collected in order to provide the flow based statistics for members on our Stats platform.

Network Config Automation

As mentioned during recent LINX meetings, we are currently implementing a network automation platform which will allow us to continuously streamline the way the network devices across all of our peering LANs are being configured. In the first phase, all member related

configurations on our Juniper based LANs will be fully automatically generated directly from the data stored in our systems. A large part of the current work consists of data clean-up that brings current network configurations in line with services documented in our systems. We are approaching the completion of this work for the LON1 LAN in London. In the longer term, this project will also allow us to open up parts of the member related configuration directly to partners and members. Examples for this are the automated provisioning of ConneXions members services, and direct access for members to adjust their MAC address filters in case of equipment changes.

Route Server Prefix Validation

As announced at LINX96 in February, we have started the work of adding prefix validation to our Route Server platforms. We are currently in the phase of doing scaling and performance tests on both Bird and Quagga platforms, and are also building the required back-end tools to support this project. Once this has been completed, we will start to verify the information we can automatically collect through a combination of PeeringDB and IRRDB databases. We will then start to contact individual members where we can not automatically gather the required details. The plan will be to then roll-out the functionality in a phased approach, across the different Route Server platforms and Peering LANs. We will provide further details at upcoming LINX meetings.

Recruitment Octavian Paller

Network Engineer The LINX Technology team has been further strengthened by the appointment of Octavian Paller as a Network Engineer. Previously, Octavian spent 18 years at BT as a multi-skilled engineer before progressing into FTTC and FTTP. He later moved into fibre testing and trials at BT’s Adastral Park. Octavian told HotLINX: “After I left BT I joined Google and worked for them doing testing, remote hands and deployment in all their European sites, before joining LINX in September last year. I’m really enjoying my new role and it’s great to be working with such a strong and knowledgeable team.”

Riccardo Verzeni

Senior Software Engineer Another addition to the LINX Technology team is Riccardo Verzeni who has joined as a Senior Software Engineer. After gaining a Masters degree in Theoretical Chemistry and Computational Modelling he took on the role of Cloud Automation Engineer at Interoute. Notable projects included creating a network api to allow users to deploy VPNs connecting cloud instances among different datacentres. Following his new appointment Riccardo said: “LINX has a great software development environment with excellent coding standards. I’ve worked on some fascinating projects so far covering the stats system backend and network configuration automation.”

Public Affairs

European Parliament officially adopts Terrorism Directive

The European Parliament has officially adopted the EU Directive on Combatting Terrorism, which is designed to give police and prosecutors across the EU the ability to “fight and counter terrorism more effectively and ensure a common response to the evolving terrorist threat.”

The Directive includes “measures against public provocation online”, which state that Member States must “ensure the prompt removal of online content constituting a public provocation to commit a terrorist offence” that is hosted in their territory, and must also “endeavour to obtain the removal of such content hosted outside of their territory.” If removing the content is not feasible, Member States may block access to the content for internet users within their territory (but only after first attempting to remove the content at source). The duty is therefore placed on the Member State to exhaust all reasonable avenues


HotLINX Issue 49


for removing the content before it can consider blocking access to it, which will be warmly welcomed by service providers.

The Directive states that such measures of removal and blocking “must be set by transparent procedures and provide adequate safeguards, in particular to ensure that the restriction is limited to what is necessary and proportionate, and that users are informed of the reason for the restriction.” These safeguards must also include the possibility of judicial redress. Importantly, the Directive also states that removal or blocking of terrorist content should be without prejudice to service providers’ protections under the EU e-Commerce Directive. This means that no general obligation can be imposed on service providers “to monitor the information which they transmit or store,” nor can they be obliged to “actively seek facts or circumstances” indicating

LINX Public Affairs

LINX Head of Public Affairs

the presence of terrorist content. Furthermore, hosting service providers will not be held liable for hosting terrorist content as long as they do not have “actual knowledge of illegal activity or information and are not aware of the facts or circumstances from which the activity or information is apparent.” This will be of great relief to Internet intermediaries. The Directive must now be transposed into national law by Member States within 18 months. However, it will not apply to the UK and Ireland as both states have exercised their right to opt-out of EU policing and criminal law measures (although they may opt back in at any time subject to approval by the European Commission, the UK has stated that it will not do so), or to Denmark, which does not participate in such measures.

Lebanon - IXP Best Practices Workshop

An IXP global best practices and technical training workshop was held 23-24 March in Beirut to bring the local peering and IX community together. This is a time of change in Lebanon with the incumbent, Ojero, working closely with other partners to facilitate a stronger peering environment. 50 experts were trained over the 2-day workshop by partners from Euro-IX, RIPE NCC, INEX, and ISOC.

Cameroon - IXP Technical Training

Using local trainers Khoudia Gueye Sy and Modou Fall, ISOC coordinated an IXP Technical Training workshop in Yaounde, Cameroon with ISOC’s local chapter and CAMIX. The workshop focused on BGP training for 22 local experts to improve local technical capacity and improve the peering environment in Cameroon.

Ghana - Peering Roadshow

ISOC’s African team conducted a peering roadshow in Ghana with GIXA and 35 local experts to discuss advanced Peering Economics, Peering DB, Peering Coordinator and Netflow and the excellent Atlas Anchor project among RIPE NCC, ISOC, and AfriNIC. The latter project is meant to help deploy Atlas Anchors in 10 African countries in 2017. This joint project has led to servers being deployed to support RIPE NCC’s anchors, improving local capacity and measurements study across the region.

Europe overtakes North America as child abuse imagery hub

The Internet Watch Foundation (IWF) – an organisation founded to remove child abuse content from the Internet – finds in their latest report published on April 3rd 2017 that Europe now hosts more child abuse content online than North America. In 2015, Europe hosted 41% of child abuse imagery content online, but that has since increased to 60% of all child abuse imagery content worldwide. This contrasts with North America, which hosted around 57% of all such material in 2015 but saw a steep decline in 2016 to 37%. The IWF found that the UK continues to host only 0.1% of all the child abuse imagery they discovered. This was achieved partly as a result of the rapid removal rate in the UK - with all such content being removed within two days, and more than half of it within two hours.

LINX Public Affairs

In Brief

Speaking to the BBC, Sir Tim Berners-Lee, regularly nicknamed the “father of the web” for his important role in the development of the World Wide Web, raised concerns over the UK Government’s desire for backdoor requirements to encryption technology. He said such measures will likely result in opposing forces to the Government being more adept at breaking the encryption than the Government itself: “Now I know that if you’re trying to catch terrorists it’s really tempting to demand to be able to break all that encryption but if you break that encryption then guess what - so could other people and guess what - they may end up getting better at it than you are”. Sir Tim Berners-Lee also described the measures as an assault on the privacy of web users, and described the recent Investigatory Powers Act – a law which requires internet service providers to monitor the web usage of users and hold all such data for six months – as “appalling”. The comments also come amidst a national debate about the relationship between the Government and encryption technologies. Home Secretary Amber Rudd is cynical towards encryption, arguing that it provides terrorists with the means to communicate online. Labour leader Jeremy Corbyn also commented on the encryption issue, arguing a balance must be struck between the right to privacy and the right to know. HotLINX Issue 49

LINX’s very first regional exchange marks 5th anniversary with the exclusive launch of new Bi-Directional Optical Transceiver service IXManchester, was officially launched five years ago on 24th April 2012. The first packets of data began to flow traffic across the exchange in early June and by July HotLINX reported that there were 12 connected members passing around 700 megabits per second of peak traffic. Today IXManchester is rapidly approaching 100 connected members passing over 35Gb/s of traffic at peak making it the biggest peering LAN in the UK outside of London. This article takes a brief look back at the history of IXManchester, its recent member conference plus the new LINX product, bi-directional optical transceivers, which will initially only be available at IXManchester.

History in the Making

The launch event for IXManchester was held at MediaCityUK, in an area once home to Salford Docks. In his opening address LINX CEO, John Souter, commented: “My personal inspiration [for a LINX regional exchange] came while at a Euro-IX forum when I was asked to speculate about the future of IXPs. I had the realisation that LINX was probably inhibiting regional peering in the UK to some degree as our focus was on London. In much the same way as when LINX formed in the 90s, traffic was still having to trombone over long distances to reach its destination.”

At much the same time the networking community in the North West were also talking about the need for a dedicated Internet Exchange point in the area. Soon after, a dialogue was opened with LINX and a community forum and steering committee was formed to help make the project a reality. UK regional peering was beginning to attract considerable interest with the independently owned IXLeeds established in 2011. When it came to planning LINX’s regional peering strategy a number of policies were adopted. A community of interest was a key requirement with support from network operators, local business and government. It was decided that any exchange should be driven on the ground by the members that use it and it should have a pricing model that encourages long-term growth. Ideally, any new IXP would be hosted in a carrier neutral data centre, so that members had access under agreeable terms. IXManchester began life in 2012 as a single Brocade RX-8 switch in the TelecityGroup Williams House data centre and over time two additional sites were added at Joule House and M247. Williams and Joule are now operated by Equinix and M247 by MetronetUK following recent acquisitions. In many ways IXManchester was a test-case to see what was possible and has proved to be a great success. Further consultations with LINX members and other interested parties were arranged following launch and in 2013 a second regional IXP was set up in Edinburgh (IXScotland). In early 2014 LINX NoVA in Northern Virginia, USA began operations and IXCardiff joined the fold in 2015. While still to be formally approved, another new exchange, this time in Belfast, Northern Ireland, is mooted for the not too distant future.

IXManchester 8

IXManchester held its eighth regional meeting at the Manchester Central Convention complex on Wednesday 19th April. In all 72 people registered in what was an extended full day programme. This included talks on dark fibre access, cybersecurity and the local data centre scene, with a panel session chaired by steering committee chairman, Mat Hattersley, also on the agenda. A range of topics were discussed including how important good local connectivity was for establishing a developer / development community. This event was the first IXManchester event to be webcast and members can view footage of the event on the LINX website:

Bi-Directional Optical Transceivers New LINX product launched at IXManchester

LINX is offering a new fibre service to members at IXManchester which utilises the benefits of bi-directional optical tranceivers.

When connecting to LINX most members connect using a fibre pair or cross connect. One fibre is dedicated to receiving data from network equipment and the other fibre will be dedicated to transmitting data to the network. Bi-directional optical transceivers (or Bi-di transceivers for short) will allow both the transmitting and receiving of data on a single fibre. This is achieved by splitting the light into different wavelengths using wave division multiplexors (WDM).

Daisy Group By Yaseen Patel, Carrier Account Manager, Daisy Group

Securing your web services Alternative Networks was Platinum Sponsor at the LINX95 member conference in November. The following month the organisation was acquired by Daisy Group and Alternative underwent a full transfer of name as of 1 April 2017. The following article, written by Yaseen Patel, has background information on the Daisy Group organisation as well as an explanation as to how you can secure your web services. With the continual push on securing your network, security teams have a monumental task of defending against the ever-increasing size and sophistication of malicious and basically undesirable traffic coming into their infrastructure. However we also need to look at higher layer attacks aimed at web services, your company window. It was noted recently that two in every three packets hitting your web services are malicious in one form or another. “So, what services can aid you in securing and having an always-on service?” We still need to have layer 3/4 protection, to protect/defend against typical and sophisticated attacks such as TCP SYN, Syn Auth, IP flood, IP Frag, Mirai, Dyn, but moving up the stack, we can look at HTTP and HTTPS protection. I imagine everyone has heard of Malvertising, and defacement of webpages, these can prevented very easily with simple health checks in your webpages.

“That is one thing to fix, what about the multitude of other things to think about and possibly deploy?” HTTP and HTTPS Get & Post, HTTP/ HTTPS invalid packets and payload, long lived sessions, header request inspection. Zero-length TCP Window, rate-based limits, erasure of header response data. Also, GeoIP, ACL, black and white filtering, use of a web application firewall (WAF), cookie tampering, forceful browsing, SQL injection, URL and URI filtering, compliancy...“What is entering and leaving through my web presence?”... and the list goes on and on. These should be all implemented if you have the tools! A second issue for web and network service monitoring is visibility of tunnelled SSL HTTPS traffic. Designed to stop ‘man-in-the-middle’ inspection, the attackers are exploiting this technology by ‘tunnelling’ attacks. In 2016 it was reported that 67% of web traffic was encrypted. This will only increase with the cost of SSL certificates coming down and Google ranking websites higher if they have a cert/HTTPs service. So, apart from some compliance restrictions, we should be inspecting this traffic to make sure that we are not allowing bad traffic in. Your security layer is going to suffer as each inspection device will need to decrypt/encrypt the traffic, and when this function is enabled, performance suffers dramatically. HotLINX Issue 49


A solution is to have a dedicated appliance that can ‘decrypt once inspect many’, this will allow your firewalls and inspection appliances to do what they are intended to do.

LINX Industry Events


Interxion cost of IP transit continues to plummet, falling by around 80% since 2010 alone. That makes transit an increasingly appealing option for many organisations, promising greater control over the enduser experience and clear SLAs, with a relatively small uplift in cost compared to public peering.

The Future of Peering environment of research and education, European IXs have a long heritage of focusing on cooperation, rather than competition.

By Mike Hollands, Director of Marketing & Business Development, Connectivity Segment, Interxion UK In little more than two decades since they first appeared, Internet Exchanges (IXs) have changed beyond all recognition. From their origins inside academia in the early 1990s to today’s community led status quo, IXs have transformed not only themselves but the entire Internet, playing a vital role in the birth of our modern digital world. The IBR-LAN is a far cry from the ubiquitous global connectivity members can now expect from the 778 internet exchange points (IXPs) worldwide. Yet, because they emerged from an


HotLINX Issue 49


Meanwhile, skyrocketing IP traffic also means choppy waters ahead for IXs. Global networks will need to support more than 1000 exabytes this year, but even that’s set to triple by 2020. Peering platforms must be upgraded and overhauled to keep pace with today’s data deluge, a process that demands significant infrastructure investment from all market participants, whether IXs or transit networks. Amidst all this, IXs also need to keep pace with commercial competitors and constantly evolving technologies. New innovations may redefine what members expect from peering services and cause a tidal wave of market disruption.

By allowing members to sidestep the effort and expense of agreeing a myriad of private network connections amongst themselves, IXs have been instrumental in driving down peering costs, increasing network resilience and improving the end-user experience. Without IXs, IP traffic would be forced to travel via slower, more expensive and congested routes to its ultimate destination via upstream transit networks – undermining the seamless access to online content and services companies and consumers now demand.

In the face of this tough competition and accelerating change, many Internet exchanges are experimenting with new strategies and seeking ways to adapt. We’ve spoken to organisations from different facets of this debate - networks, content providers, commercial peering companies and IXs themselves - to examine the forces driving change and how the peering market is reacting.

While public peering is a young industry, it’s moving fast and reinvention is already on the horizon. Today, several factors are converging that leave traditional, member-led IXs in the midst of a perfect storm. Pricing is perhaps the most obvious wave on the horizon. The

3 is the Magic Number By Ben Hedges, Chief Executive Officer, LINX America

LINX NoVA has performed extremely well in the past year but in April 2017, the month we celebrated the exchange’s third birthday, things have really taken off. Firstly we achieved a new peak traffic high of 15.79Gb/s and NoVA is now second only to LON1 on IPv4 prefixes on the route server (45,000). April was a busy month for events too. Hostingcon in Los Angeles and GPF12.0 in New York went particularly well with a great deal of interest in LINX NoVA. This gives me real confidence for the rest of the year and beyond as we close in on 50 connected ASNs. Not only that, we also have 11 prospects who are also considering connecting in London. It’s pleasing to see LINX America bringing benefits to the whole membership and not just those active in North America. As I said earlier, LINX NoVA has just reached its third anniversary and to mark the occasion we have announced a special birthday offer. Any new LINX member who applies before 30th June 2017 who wants to connect to LINX NoVA will receive 2 months free membership and port fees. See the panel on the right for more details. All in all it’s definitely an exciting time for LINX NoVA and the future looks very bright indeed.

LINX NoVA is the largest multi-site peering LAN in the Washington DC and Ashburn district SPECIAL OFFER To celebrate LINX NoVA’s 3rd birthday LINX is offering 2 months free membership and port fees for new members wanting to connect to the LINX NoVA exchange!

To raise awareness among companies and organisations about the new domain extensions the registry conducted a promotional campaign on and some months ago to showcase the new registrations, in particular through the social media. More info on GeoTLDs can be found on page 5 of HotLINX.

Dyn Research and Spiceworks recently published the results of an Internet Disruption research study, which tracked the experience and opinions of in excess of 200 IT professionals in the UK and North America. It was discovered that nearly 90% of the companies asked had experienced some form of Internet disruption during 2016. When asked, “How painful was the disruption to your organization and you/your team?” most of those surveyed said that when disruptions did occur the impact was substantial.

Not Cool: 89% Of Companies Experienced Internet Disruption In The Last Year

In the Spotlight with Bijal Sanghani Secretary General of Euro-IX, the European Internet Exchange Association

HotLINX Editor, Jeremy Orbell, speaks with Bijal Sanghani, Secretary General of Euro-IX, to discuss her role and how the organisation is encouraging stronger links between Internet exchange points worldwide. First of all please tell us about background in the telecoms industry and career to date. After gaining a degree in Mathematics and Computing at Middlesex University in the mid-90s I took up a position at DEMON Internet as Hostmaster. After about a year I moved to Level 3 where I was a provisioning engineer before undertaking IP support and network engineering roles at FLAG Telecom and Sohonet respectively. In 2005 I joined Reliance Globalcom, initially as a technical support engineer in operations, and then as a solutions engineer. It was from here I joined Euro-IX as the Head of the Secretariat in 2011. I’ve also been RIPE NCC Working Group Chair since 2004. How did you come to be involved with Euro-IX? Prior to being involved with Euro-IX I was working with many Internet exchange points through my day-to-day work. When the position became available it was timely because I was looking for a new challenge so put myself forward and was interviewed for the role by Euro-IX Board members Job Witteman of AMS-IX and John Souter of LINX who then appointed me. What exactly does your role as Euro-IX Secretariat entail? Euro-IX is now a membership organisation of over 80 IXPs, not just Europe, but from all around the world. For that reason alone I’m certainly kept busy! One of the key things we’re trying to do is build on the services we have and also grow the membership because the more exchanges we have on board the more experience

and knowledge we can share amongst the community. We have a monthly newsletter to keep our members informed of activities and we host two forums a year. In fact we’ve just had one in Barcelona which saw a record 48 IXPs attend, and to get that many together in one room was very special. Euro-IX is also the secretariat for IX-F, which is the Federation of Internet Exchange Points, which comprises of representatives from four global IXP Associations. In addition to Euro-IX these are APIX (Asia Pacific Internet Exchange Association), LAC-IX (Latin America & Caribbean Internet Exchange Association) and AfIX (African Internet Exchange Association). Each one has its own administrator to provide administrative support within the defined work areas of the Federation and I carry out that role on behalf of Euro-IX. Working together helps feed another key project which is our IXP database that now forms an important part of our new website. Some of the tools we have are an IXP Directory, an IXP Service Matrix and Peering Matrix as well as an ASN Database. You mention that Euro-IX is not just about European exchanges. I understand that JPNAP from Japan were one of the first join. Yes, that’s right. We actually have three IXP members from Japan now and one from Brazil who were also early non-European members. To have members from these countries and other international territories prepared to travel such distances to attend the forum in person certainly demonstrates the value they are getting from these events. HotLINX Issue 49

At the Euro-IX Forum in Poland last year LINX’s Malcolm Hutty was presented with an award for his regulatory work for the association Indeed he was. He is Euro-IX’s regulatory officer and the award was an acknowledgement of his extensive knowledge and contribution to Euro-IX, and the wider membership, over many years. His advice continues to be invaluable and his involvement in our mailing list on these issues just adds another dimension to the services we are able to offer our members. Peering forums have been taking place for more than a decade now and that is another form of IXP collaboration. What do you think about these particular events? I think they are great because they bring together the wider Internet community and make it easier for interconnection to happen. We always talk about peering being done over a handshake and these kind of events that promote that. There are so many now however but that just proves how successful they have been for the industry. There are now over 500 Internet exchange points in the world with more and more new ones being built in cities and countries which haven’t had an exchange before. Euro-IX, in fact, has a fellowship programme where established IXPs are mentoring these fledgling exchanges. For example, LINX is a mentor ZIXP, the Zambian Internet Exchange. In Barcelona we had guest IXPs from Costa Rica, Ecuador, Pakistan, Kenya and the Republic of Congo. The benefit for them is that they are not only able to learn, but they can take back that knowledge and experience to their regions and IXP associations. This also helps them improve their own events and meetings as well. What plans do Euro-IX have in the immediate future? This summer we are looking to organise a series of workshops and hackathons which is part of a goal to bring our members together outside the main forums. The aim is to collectively solve common technical issues that exchanges may be facing. We’re looking at the BIRD route server as one such workshop to identify additional features we can use and developments to looking glass facilities. All the relevant details will be announced on our website in due course at
