Across the world, nations are going dark. Countries, fearful of their own populations, are cutting their citizens off from the net in an effort to quell protests and stifle free speech. For the cover feature of DCD Magazine, we talk to protesters in Hong Kong who fear the end of the open web, journalists in Kashmir who have gone months without a connection, Estonian cyber security professionals preparing for a Russian invasion, the CTO of Cloudflare, CEO of ThousandEyes, researchers from around the world tracking everything from Indian protests to Russian cyber laws - and more. Elsewhere in the magazine, we talk to OVHcloud's CEO, head to a genome sequencing data center, study how AWS secretly raised prices, and learn why you should build data centers with AI in mind. Plus, in a jam-packed Telco supplement, we explore 5G, the CORD initiative, space-based Internet and much more.
