A massive chunk of the internet dropped offline Tuesday morning. Outages were reported on the sites of many of the world’s biggest publishers, including The New York Times, CNN, The Guardian, the Financial Times, and parts of the BBC. Reddit, Spotify, Twitch, some parts of Amazon, and the British government’s main website were also returning error messages. TechCrunch reported that an outage on Fastly—a widely used CDN provider—appeared to be the cause of the major global blackout, and Fastly wrote on its site that it’s investigating an unspecified problem that is creating “potential impact to performance” for its big-name clients. Around 50 minutes after it first identified the issue, Fastly wrote: “The issue has been identified and a fix is being implemented.” Some of the sites started reappearing online after that message was posted.
