GLOBAL GLITCH: SWATHS OF INTERNET GO DOWN AFTER CLOUD OUTAGE

Dozens of websites went down briefly around the globe Tuesday, including CNN, The New York Times and Britain’s government home page, after an outage at the cloud computing service Fastly, illustrating how vital a small number of behind-the-scenes companies have become to running the internet.

The sites that could not be reached also included some Amazon pages, the Financial Times, Reddit, Twitch and The Guardian.

San Francisco-based Fastly acknowledged a problem just before 6 a.m. Eastern. About an hour later, the company said: “The issue has been identified and a fix has been applied.” Most of the sites soon appeared to be back online.

The company said in an emailed statement that it was a “technical issue” and “not related to a cyber attack.”
