A massive internet outage has affected websites including the Guardian, the UK government’s website [gov.uk](http://gov.uk) , Amazon and Reddit. The issue made the sites inaccessible to many users for more than an hour on Tuesday morning.
The outage was traced to a failure in a content delivery network (CDN) run by Fastly. It began at about 11am UK time, with visitors to a huge number of sites receiving error messages including, “Error 503 service unavailable” and a terse “connection failure”.
Others affected included the publishers CNN, the New York Times, and the Financial Times, as well as the streaming services Twitch and Hulu.
As well as bringing down some websites entirely, the failure also broke specific sections of other services, such as the servers for Twitter that host the social network’s emojis.
