Reflections on 2016 & Plans for the New Year By John Souter, LINX Chief Executive Officer As 2016 has now come to an end, I have chosen to use my HotLINX introduction to reflect a little on the year gone by. It has certainly been a busy year for international travel with three trips to the USA, all centred around North American Network Operators’ Group meetings. NANOG has always been an important part of the LINX calendar and we are pleased to say that we will be the local host for NANOG 69 in Washington DC this coming February. September marked the tenth anniversary of the very first European Peering Forum which, this year, was held in Sofia in Bulgaria. LINX co-hosts EPF with AMS-IX, DE-CIX and Netnod and on this occasion it was our turn to be lead organisers. I was delighted that we had a record attendance with registrants topping 300 for the first time. Also in the Autumn I visited Paris for the France-IX AGM, where I spoke about our future collaboration plans, and followed that with a trip to Prague in the Czech Republic to help mark NIX.CZ’s 20th anniversary. We have worked with NIX.CZ for many years and their BIRD routeserver project has proved so successful for us that we decided to award them with the Conspicuous Contribution to LINX Award a few years back. Closer to home it’s been another good year for our quarterly member conferences with some impressive attendee numbers. Indeed, at LINX95 in

November numbers topped 200 which even necessitated a spin-off evening social as we were over-subscribed! LINX95 was a great event all round and I was able to have excellent one-to-one discussions with the Chief Executives of our new vendor partners, IP Infusion and EdgeCore. We are very excited to be working with them both on our LON2 architecture refresh this year. It was announced at the November member conference that Telehouse inter-building fibre cross-connects without any recurring charges had been agreed, which is a great breakthrough for us. We also formally announced the launch of our IXP Reseller product which will allow new member networks to connect to the exchange through an alternative local IXP in their region. These are just two ways in which we are trying to make things easier for networks to connect at LINX. One final event I will mention is the launch of Telehouse North Two data centre in Docklands. As we know Telehouse is where LINX began all the way back in 1994 and to be asked to be part of the VIP panel for the official launch was a great honour. It’s been a great year. We have nearly 750 members from 72 territories now and have had well over 100 member applications over the past 12 months. I look forward to reporting even bigger numbers in 2018.

Editorial HotLINX stats and research

By Jeremy Orbell, HotLINX Editor In an earlier editorial column I stated that we would be conducting research on what members wanted from HotLINX. The first stage of the process included asking a number of questions as part of our recent membership survey. Here’s what we’ve discovered so far. First of all 61% of respondents read the magazine in either either printed form or electronically - with more than 56% choosing do so online. 74% felt that quarterly is still the right frequency for HotLINX. We also asked what content readers would like to see featured. Responses included: • New developments, threat mitigation strategies • Current network operator concerns • New technologies on the LINX LANs. • Regional and global internet concerns that may affect members • Policy, internet evolution and innovation, relevant tech tips • Peering opportunities and network optimisation • Security We always want your feedback so if there is content and features you would like to see included then now is most definitely the time to submit them.

Happy New Year!

Industry News Funding boost for Broadband in UK’s remotest areas In the region of 600,000 homes and businesses could connect to superfast broadband, after £440m was recouped by the UK government. £150m is the result of cost savings and returned subsidies from BT accounting for the remaining £292m. Culture Secretary Karen Bradley has stated that the capital would see some of the remoter parts of the UK benefiting from faster broadband. The government had paid BT to roll out superfast broadband in hard-to-reach areas as part of a deal struck in 2010 after providers had said installing broadband infrastructure in those areas was not costeffective. Under the terms of the agreement, if in excess of 20% of premises in those areas bought superfast broadband, BT was required to repay some of the subsidy. According to the Department for Culture, Media and Sport the take-up has been in-fact 30.6% resulting in a forecast repayment of £292m. Andrew Ferguson, consumer telecoms expert at Think Broadband commented, “This is not £440m of new money” but regardless of the source, more funds going into infrastructure was “good news”. Meanwhile, Kim Mears, managing director for infrastructure delivery at BT’s Openreach division, said that while there was “still more to be done” to improve rural broadband speeds, 4.5 million rural homes had already benefited from BT’s efforts.

Interxion Paper: The Future of Peering

With falling transit costs and an increasingly competitive marketplace, Internet Exchanges are facing unprecedented challenges. One of LINX’s data centre partners, Interxion, has published a paper which seeks to predict what the future holds for peering. In compiling the document Interxion sought contributions from a number of influential members of the peering community. These included Kurtis Lindqvist (LINX), Richard Irving (LONAP), Gaurab Raj Upadhaya (Limelight Networks), Neil McRae (BT) and Mark Cooper (Megaport). Amongst the findings it was found that some networks would be looking to cut costs and reduce overheads while others believed that new market expansion and improved member services were essential to long-term success. Whatever the future holds, the industry faces some tough choices which will ultimately drive it towards greater cooperation or competition. Readers can download the paper from the Interxion website here:

In Brief Digital Infrastructure Boost in Chancellor’s Autumn Statement

In his first Autumn Statement in November, Chancellor Philip Hammond pledged to invest more than £1bn in the UK’s digital infrastructure. Of this investment, £400m has been earmarked for a new Digital Infrastructure Investment Fund with an additional £740m committed to the advancement of 5G and full-fibre connections. Hammond stated that for the UK to be a global leader in 5G it needed not only a full-fibre network, but enhancements in speed, security and reliability. To do this a world-class digital infrastructure to underpin them was required. Among the measures announced were 5G network trials plus support for the private sector in developing full-fibre broadband by 2020-21. The government is also planning to introduce a new 100% business-rates relief for new full-fibre infrastructure for five years from April 2017.

Raspberry Pi makers release own-brand OS

The makers of Raspberry Pi have developed a version of Pixel desktop, the mini-computer’s graphical front end, that runs on both PCs and Apple Macs. Eben Upton, Raspberry Pi’s co-creator, said the software should help schoolchildren who use the Pi in class or for their own projects but have to continue their work on PCs or Macs. “There is no learning curve, and no need to tweak” Upton said. The Pi edition of Pixel uses “exactly the same productivity software and programming tools, in exactly the same desktop environment”.

What they’re saying Telehouse Inaugurates New Highly Connected Data Centre in Docklands

Greg Hands, Minister of State for International Trade “Telehouse’s decision to make the UK its European hub of operations is a testament to our strong and growing digital economy. As a pioneer in the data centre sector, this new data centre located within Telehouse’s historic Docklands campus will provide unrivalled connectivity, contributing to the UK’s long and strong history in innovation.” Mr Hands continued: “It’s great to see this company’s continued investment in the UK and I’m pleased the Department for International Trade has been able to support them throughout this process. I hope that more international companies follow their lead and take advantage of the many strengths that make the UK a great place in which to invest.”

Telehouse North Two

Koji Tsuruoka, Ambassador of Japan to the United Kingdom “Prior to the North Two launch event I realised that behind all of the emails we send and receive and all the activities companies run, the infrastructure and service Telehouse provides here in Docklands supports every aspect of our life. I also learned that Telehouse supported many companies involved in providing digital content services during the London Olympic Games, which was watched by people all over the world. With this current unpredictable age and the anticipated potential impact of Brexit, it is really reassuring to know that KDDI-Japan has made such an investment in London.”

LINX News LINX95 EGM & Governance Consultation Review

At the LINX95 EGM the membership formally voted on a number of resolutions, notably the 2017 fees schedule and annual budget. Other resolutions seeking approval covered subtle but important wording changes to the LINX Memorandum of Understanding (MoU) plus remuneration for the LINX Council for the year. All five resolutions were passed with each achieving higher than 96% of votes in favour. The LINX website has consequently been updated to reflect the changed MoU and fees schedules which came into effect on 1st January 2017. The new fees can be viewed at:

A number of possible governance changes were also discussed at LINX95 in a session chaired by LINX Chairman, Murray Steele. The key aim of the consultation was to put forward the proposal that the LINX Board be expanded to include up to three Executive Directors in addition to the CEO. Murray explained that the role of

elected non-executive directors (NEDs) should be protected to ensure LINX remains true to the principle of mutuality, and honours the interests of its members. The proposals covered whether to alter the relative timing of Board elections and hustings, the introduction of vetolike reserved powers, the threshold for suspending a Board majority decision to “at least 50%” of elected NEDs and that the membership should be able to override the reserved power so as to authorise the Board majority decision. In addition the proposals covered whether to alter the relative timing of Board elections and hustings. Formal ratification of the key proposals will be put to a membership vote in another EGM on 22nd February. The LINX95 governance session video can be viewed on the LINX website: (log-in required)

NaMeX signs as first LINX IXP Reseller partner

LINX has added another service to its growing product portfolio. The new product, labelled IXP Reseller, will allow new member networks to connect to LINX through an alternative local exchange in their region, thus giving them access to the array of benefits and services that LINX has to offer. The connection is made via one of LINX’s existing resellers meaning the member has just a single invoice to pay. Rome-based Nautilus Mediterranean eXchange point (NaMeX) is the first to sign up as a LINX IXP Reseller partner. Luca Davoli, Director of Strategic Alliances at NaMeX, said, “Becoming a LINX IXP Reseller means NaMeX is able to offer networks a convenient connection point to the UK whilst also strengthening our service offering in our own region.” LINX Chief Marketing Officer, Kurtis Lindqvist, added, “We are very excited by the new IXP Reseller product and are delighted to welcome NaMeX as our first partner. We have been in discussions with other European exchanges and expect to be able announce further agreements shortly.” For more information on IXP Reseller please visit:

National Cyber Security Centre (NCSC)

UK Government publishes its National Cyber Security Strategy The UK Government has launched its new five-year National Cyber Security Strategy stating that it will spend a total of £1.9 billion over the next five years to realise its vision that by 2021 “the UK is secure and resilient to cyber threats, prosperous and secure in the digital world”. This vision is built on three pillars: Defend, Deter and Develop. The Strategy states that Government will play an expanded role in driving change in cyber security in the UK with a focus on the following four broad areas.

Levers and incentives The Government “will invest to maximise the potential of a truly innovative UK cyber sector” by supporting start-ups and investing in innovation. The Government will also “make use of all available levers, including the forthcoming General Data Protection Regulation (GDPR), to drive up

Expanded intelligence and law enforcement focus on the threat The intelligence agencies, the Ministry of Defence, the police and the National Crime Agency “will expand their efforts to identify, anticipate and disrupt hostile cyber activities by foreign actors, cyber criminals and terrorists.”

Development and deployment of technology in partnership with industry The Government will adopt Active Cyber Defence measures, which will include working with Communication Service Providers

LINX Public Affairs

The Government has established a single, central body for cyber security at a national level. The NCSC, which is part of GCHQ, will “manage national cyber incidents, provide an authoritative voice and centre of expertise on cyber security, and deliver tailored support and advice to departments, the Devolved Administrations, regulators and businesses.” In addition, the NCSC will define clear processes for reporting incidents, which will help to facilitate a single-joined up approach to incident management.


The Strategy acknowledges that “the science of cyber security has been obscured by hyperbole and obstructed by an absence of calibrated data.” As a result, Government states that it “will ensure that this strategy is founded upon a rigorous and comprehensive set of metrics against which we measure progress towards the outcomes we need to achieve.”

APNIC will provide training prior to the forum and the forum itself focuses on developing a new bottom-up IXP and building the IX and interconnection community in Kolkata. Stay tuned for registration information very soon! Kyrgyzstan – April 2017 ISOC will continue training with regional experts to continue to develop the IX community and technical expertise.

Ofcom to order “legal separation” of Openreach from BT

Ofcom has decided to order BT to separate its Openreach division into a legally separate subsidiary company. The new Openreach would have its own Board of Directors and its own balance sheet. It would still be wholly owned by BT, and it is not clear how much day-to-day authority BT would have over its subsidiary. The move, called “legal separation”, would stop short of full structural separation in which BT was required to divest itself of Openreach entirely, but is viewed by some as a step towards that end. The decision requires the approval of the European Commission. BT has said it still hopes to achieve a “voluntary settlement” with Ofcom, noting that Ofcom has said it remains “open” to further proposals from BT to address Ofcom concerns.

In November the Internet Society announced that its prestigious Jonathan B. Postel Service Award had been presented to Dr. Kanchana Kanchanasut, a leading computer scientist in Thailand and Vice President of Research at the Asian Institute of Technology (AIT). The award was presented for her pioneering work in establishing the Internet is Southeast Asia and for enabling countless others to spread the Internet across the region. Dr. Kanchansut was selected by an international award committee comprised of former Jonathan B. Postel award winners. The committee placed particular emphasis on candidates who have supported and enabled others in addition to their own specific actions.

In Brief

US transfers ICANN oversight to global Internet community

On Saturday 1st October, the US allowed its contract with ICANN for performance of the IANA technical functions to expire. This completes the process for transferring oversight of ICANN from the US government to the global Internet community. Transfer of ICANN oversight was first envisaged 18 years ago, as a policy of the Clinton administration, and was revived in March 2014 when U.S. Department of Commerce agency the NTIA asked the global Internet community to come up with a plan for taking responsibility for the IANA functions and overall oversight of ICANN. Since then a massive community effort involving hundreds of people, dozens of physical meetings, thousands of man-hours and tens of thousands of e-mails assembled a complex plan to replace the US role with global multistakeholder oversight.

Technology Matters

With major network upgrades and the introduction of a new LINX NOC, it’s a time of change for the LINX Technology team Each issue of HotLINX features an article focussed on the activities of the LINX Technology team. These typically cover improvements to the network’s infrastructure, proof of concept testing plus future plans. With the upgrade of the LON2 network in full swing, and the imminent introduction of LINX’s own NOC team, it was felt this was a good time to give the department some additional exposure. LINX Network Enginering Manager, Mike Hellers, takes up the story.

Finishing up 2016, and Preparing for 2017

The last weeks before the annual network freeze, around the end of year holidays, have always been a busy period for the LINX Technology team. After the successful deployment of our first High-Density Edge router on the LON1 (Juniper) LAN, we have now moved a number of 100G member ports from the existing Edge routers to the new MPC7 based router. This provides capacity gains through aggregation and also frees up valuable rack space at the site due to the higher slot capacity on this latest generation of line cards by reducing the number of edge routers required. As mentioned in previous updates, these routers are connected with 2x24x40G, providing close to 1Tbps of protected capacity to the core of the network. The LON1 core network topology change was completed in early December, regrouping the core links, providing us with better use of the available capacity, and as such indirectly increasing the amount of usable capacity between the core sites.

LON2 architecture upgrade explained in two specially recorded videos

It was announced at LINX94 in August that LINX was to use new hardware and software on its secondary London interconnect platform, LON2. The last issue of HotLINX covered the technical background to the move and the state-of-the-art routing technology it will use. In order to explain these developments in a little more detail LINX Chief Technical Officer, Richard Petrie, recorded two videos which have since been published online and shared across social media.


HotLINX Issue 48


Inside Story: LINX Technology

Mike Hellers, LINX Network Engineering Manager

As mentioned during LINX95, we have seen an increased demand for member capacity in our site at Equinix in Slough. Over the past weeks we have worked with Equinix and have agreed an option for additional rackspace, allowing us to install a second edge router for LON1. During December we started the preparation work for this upgrade, which included finalising the network design and project plan for readiness of the new rack foot print. Installation of the structured cabling between the existing and the new rack has been completed. Last but not least, some the additional equipment, which includes an MPC7 based MX960 and optical transport equipment, has also been installed. During the first weeks of January, we expect to bring this new rack into service and also significantly increase the capacity between Slough and the core of our network. We aim to have the additional capacity available later in the month. In parallel, we are also upgrading the capacity available on the LON2 switches at that site.

Over the last few months, as part of the network refresh of the LON2 network, we have been evaluating and testing next generation 100G capable optical transport equipment. We will deploy the selected DCI (Data Centre Interconnect) transport platform to deliver the capacity upgrades to Slough, which will allow us to deploy 10/40G/100G circuits over 200G coherent channels, while maintaining our existing DWDM MUXs. Using the new platform brings the benefit of future proofing these upgrades and also serves as a first trial deployment ahead of the LON2 network refresh later in the year. We will provide more details about the solution and the implementation in the next HotLINX issue and also at LINX96 in February.

Dedicated LINX NOC team to begin operations from January 2017

As LINX has grown we’ve identified the need for additional support for our oncall engineers, first with NetSumo taking calls out of hours in 2009, next with Allegro/Console taking calls and tickets 24/7 in 2014. We are now able to announce that we’re bringing the NOC inhouse to expand the scope of what the NOC engineers can assist with, including monitoring network issues and working closely with the LINX engineers. This works along with our evolving strategy and adoption of automated and intelligent tools and being able to train the NOC to a higher technical standard thereby, improving service capability and the membership experience. The NOC engineers are currently in training and are planning to take over from the Console NOC on 9th January 2017 with the Console NOC shadowing them. Over time, the plan is for them to take on more responsibility with network issues, triaging, fixing what they can and escalating to the oncall when needed. The NOC Engineers will also support our internal network infrastructure and escalate to the oncall IT engineer when necessary. They will eventually be able to assist with remote hands issues out of hours as well. “I am very pleased to introduce our new team of NOC engineers. They come from various backgrounds and have different strengths, which complement each other. As I get to know them, they’re gelling as team that works together” Anne Bates, Network Operations Manager

Kentik It’s Time for Big DataPowered DDoS Protection out of date objects for baselining, and segmented rather than network-wide views of network data. The result is fairly significant inaccuracy in detecting attacks.

Big data to the rescue By Jim Frey, VP of Strategic Alliances, Kentik The last year has shown us that there’s no place for complacency in dealing with DDoS. It’s time to move to the next generation of detection based on cloudscale, big data architectures. In the prevailing out of band model for DDoS protection, a server appliance detects attacks based on NetFlow, sFlow, IPFIX, and BGP data. This appliance then signals the network to either drop traffic at the network edge or redirect traffic to a mitigation device. This approach has been in place for well over a decade. The dirty secret is that appliance-based systems are plagued by vexing detection accuracy issues due to the compute and storage limitations of scale-up design. Legacy detection software typically runs on a single, multi-core CPU server using some Linux OS variant. Confronted with a massive volume of flow records, these servers must apply nearly all of their compute and memory to unpacking data from UDP, converting binary to ASCII data, and storing it in a high-latency relational database. That leaves traditional detection appliances with precious little left over to operate detection algorithms. Because of this, the state of the art in appliance-based detection leans on simplistic static thresholds, small pools of statically configured and constantly

How do we get beyond the inaccuracies in legacy DDoS detection systems? By recognizing that DDoS is a big data problem and removing the constraints of scale-up architecture. The fact is that there are billions of traffic flow records to ingest and millions of IPs that need to be tracked individually and measured for anomalies. Luckily, cloud-scale big data systems enable a far more intelligent approach to the problem:

About Kentik Kentik is the network intelligence company, offering the industry’s first purpose-built big data engine that turns huge volumes of NetFlow, BGP, performance metrics and other network data into operational insight and DDoS protection. Kentik Detect unifies multiple, silo’d tools into a powerful platform that help you deliver an optimal network experience to your customers.

Kentik Detect stores months of instantly accessible, online raw flow records, and offers: • Ad-hoc, multi-dimensional traffic analysis on multi-billion row datasets in seconds

• Monitor network-wide traffic from millions of individual IP addresses with ease • Simultaneously track and assess multiple data dimensions and dependencies • Automatically recognize and baseline any end address that exhibits anomalous behaviour.

• Adaptive anomaly and DDoS detection, along with automated attack mitigation via RTBH and leading mitigation products • Cloud-friendly network performance monitoring • Powerful network planning and BGP peering analytics visualization

This scalable, adaptive approach to monitoring and anomaly detection has been field-proven to be far more accurate than legacy approaches. We’ve seen deployments reporting greater than 30 percent improvement in catching and stopping DDoS attacks (i.e. less false negatives) since taking a big data approach.

Offered as an easy to use SaaS, Kentik Detect can take you from registration to production in 15 minutes with no hardware required. Learn more at and start a free trial.

Even better, big data is the ideal way to not only detect and stop DDoS attacks, but to get deeper analytics for operations and planning as well. HotLINX Issue 48

LINX NoVA News 100G boost for LINX NoVA By Ben Hedges, Chief Executive Officer, LINX America As we approach the end of the first year of having feet-on-the-ground in the USA, I wanted to reflect back on how things have progressed over the previous 12 months. As you know, a successful exchange of traffic needs eyeballs and content on either side of the equation, so it was with much pleasure we welcomed our first large access provider, WOW!, to LINX NoVA in April. Since then, we have seen a steady increase of participants at the exchange which has naturally also seen an increase in the number of packets passing between members.

Ben Hedges

CEO LINX America

Michael Kennedy joins us as Head of Sales and Kendra Pignotti as Business Administrator. Both will be headquartered out of our Ashburn office with me.

At the time of writing we have 31 networks connected to the exchange with a further 6 in provisioning, including the first 100G port order for the LINX NoVA exchange. Growth in 2016 has exceeded our expectations and puts us in a great position going into 2017 to deliver more value to members even faster than we had hoped. In preparation for the increase in demand we are expecting we have added two new members of staff to the LINX America team (pictured right).

Finally, I am delighted to let you know that we have simplified our service fees for 2017 and will be continuing to support members as we build to critical mass by retaining the traffic trigger promotion.

DNS Belgium: The Future is Virtual The DNS Belgium registration platform for registrars is currently located on a cluster of physical servers in two data centres. They are currently busy writing the software to host the registration platform on which new .be domain names will be registered, in the cloud. “The idea of virtual hosting of programmes, platforms and applications is not new. Consider the app of a bank, for instance. It is entirely in the cloud. But it is new in our sector,” says Philip Du Bois, General Manager of DNS Belgium. “We are thus playing a real pioneering role in Europe, perhaps even in the world, with regard to our peers in other countries.” DNS Belgium conducted a thorough analysis of the availability, functionality, services and security before opting for the cloud, which offers many advantages compared with conventional hosting on physical servers. “For instance, if parts of the registration platform should fail, we can restore them rapidly in another virtual environment. We no longer need to maintain certain operating software and patching ourselves, and there is a lower risk of security infringement by comparison with the current hardware set up. This switchover will have only positive consequences: higher security and even better availability.” To read the full story please visit:

Packet Clearing House


Packet Clearing House (PCH) provides support both to Internet exchange facilities in the process of formation and to those that are already up and running.

On the occasion of the 20th anniversary of Czech exchange, Netnod were proud to deliver a special gift: an “Instant I-root”. This will be installed at new exchange in Bratislava, Slovakia. Netnod operates i-root The only thing needed now is to one of 13 logistical DNS add hardware (a server) and then root name servers. it’s up and running. director Martin Semrad said, “This is a great opportunity for making the Internet in Slovakia more robust”. Netnod’s Alexander Borodin added, “Both Netnod and celebrated twenty years of operations in 2016 but our organisations are looking to ‘Peer in to the future’ reflecting the slogan Netnod uses in our marketing”.

Internet Exchange Points

Although they supply the switching equipment that forms the technological core of exchanges, often their most valuable contribution is in the form of education, technical expertise, and mediation with policy and economic officials of the local government.

In the Spotlight

Equinix. These end customers are the ones who are spending the money on IT to deliver to the consumer products and services. This change is accelerating and becoming massive. The financial services and healthcare sectors, plus many others, are in turmoil and are being forced to transform themselves. Almost every one has elevated the CIO to lead partner in that transformation. The question to ask ourselves is are we fit for purpose in this new world order.

with Michael Winterson Managing Director, Equinix Services Limited

HotLINX Editor, Jeremy Orbell, speaks with Equinix’s Michael Winterson to discuss the recent acquisition of TelecityGroup, the issue of fibre tax in the UK plus Equinix’s relationship with LINX. First of all please tell us about how you came to work for Equinix My first day at what is now Equinix was January 1st 2000. I’d had a working relationship with some start ups and the founders of IXEurope, as it was then known, called me in when they’d raised the first round of capital and the first data centre was built. There’s still a core group of 7 or 8 from the very first day at Equinix. It has been a fun company to work with who have thrived on the challenges of being a growing, global organisation. Equinix recently completed the takeover of TelecityGroup. How did the process evolve? The Telecity negotiations began in the Spring of 2015. It took longer than we’d hoped because the deal was brought in front of the Competition Commission of the European Union but that was to be expected. What the management teams of Telecity and Equinix knew from the beginning was that our business models were very closely aligned. We launched Cloud Exchange and Telecity launched CloudIX and we both knew that our businesses were undergoing a huge transformation - to us the acquisition made a lot of sense. It opened up the combined group to significant new markets and while there was customer overlap, it still added 800 new customers to our portfolio plus seven new metros. Metro coverage is going to be critical for the future of where we see the data centre business going. You presented at the LINX94 conference in August. How useful was it to meet with the members? I was delighted to be asked to speak and explain the current position with the acquisition. We said, look, there are many things that Telecity and Equinix do well but by combining the two we get the best of both. Where I think I perhaps failed in August was in trying to tell a story of how radically we think the data centre industry is

being forced to change. At my meeting with LINX in December we covered LINX’s own strategy and it was clear that they are seeing this change as well. LINX, Equinix, other peering platforms, as well as members, are all affected whether they realise it or not. For example, I was very impressed by the BBC presentation at LINX94 on the streaming of data and how important streaming technology is to them now. From being 100% broadcast they’ve had to radically change how they operate in the space of 10 years. How do you see the data centre industry and Equinix developing? At Equinix we see the future of the data centre industry in delivering access to enterprise to business consumers of data centre services. Data centres were almost exclusively selling into the service provider community and Equinix are now being able to present itself to an enterprise as a key part of their IT strategy. Behind that we still have over 6000 service providers as customers and we want to make sure we provide an excellent service. I believe we are respected in being able to put the right capital up to building good data centres and our operational record is very reputable, even market leading. However, when we do have a problem, such as the London outage earlier in the year, our response is unequivocal, rapid, and strong. We spent a lot of money immediately upgrading and replacing the Harbour Exchange equipment that hadn’t worked and, as a safeguard, we replaced similar equipment that had been unaffected. We’re finally seeing the digital transformation people have been talking about for 5 or 6 years taking root. I’m meeting with enterprise clients who are ripping out 30 year old technology and replacing it in the space of 12 to 18 months. To a global enterprise this is radical. They are embracing IoT, apps development, and these are truly the end customers of LINX members, including us at HotLINX Issue 48


What are your views on the UK government’s tax on fibre optics? We need to take this in the context of the UK as a leading service economy and a country that states that it wants to be at the cutting edge of technology. It claims that it has the highest concentration of technology companies and start ups and developers outside of Silicon Valley and yet the government has some policies that make you wonder if they realise they are in fact slowing things down. Why would you tax fibre optic networks in such a way that a company takes on a tax liability in advance of delivering any business service over it. Furthermore it slows down the adoption of high bandwidth products and services that UK specifically says it wants to deliver to its people. I can’t imagine that the fibre tax revenue itself offsets the penalty that the UK government is putting on the UK population. In a competitive market like the EU there are plenty of other countries that companies could choose to colocate their technology. Editor’s Note: A concession on fibre tax was made in the Chancellor’s Autumn statement but details are yet to be finalised. What about the future together for LINX and Equinix? At my last meeting with LINX we spoke about how we need to engage more with leading banks, healthcare companies and enterprises on what peering is. What can you do with it? How can it solve network optimisation issues with apps or IoT strategies, or because you want to harmonise public cloud with your old technology. We’ve got to go out and speak to new people who don’t have the same level of understanding and bring them up to speed. It’s difficult because many are afraid of change. They’re curious but to them the Internet community is still novel. There is prejudice but maybe they are just insecure. They are perhaps worried about darknet, DDoS and fraud etc and yet the Internet is very closely aligned with what they need as businesses. However, it requires skillsets that these companies often don’t have. We can help them overcome these issues together. In the Spotlight: Michael Winterson
