Stuff that happens while I'm sleeping!

Websites around the world, including major news sites, Amazon and the United Kingdom's government page, were temporarily down during a massive outage early Tuesday.

Fastly, an American cloud computing services provider, said it began investigating the issue about 5:58 a.m. ET on its status page. The company, which provides content delivery services to many websites, provided an update an hour later.

"A fix has been applied," Fastly said. "Customers may experience increased origin load as global services return."

It was not immediately clear what caused the massive outage.

Multiple news outlets were taken offline, including BBC, Bloomberg News, CNN, The Financial Times, The Guardian, The New York Times and The Verge. Other websites like Reddit, Pinterest and Twitch were also affected by the outage. Amazon's and Target's retail websites and the U.K.'s government website — Gov.uk — were not working at some point, too.

"The Guardian's website and app are currently being affected by a wider internet outage and will be back as soon as possible," the outlet said in a statement on Tuesday.

The Verge, which was down for more than hour, got creative with sharing their outage news.

"Vast chunks of the internet are offline, including The Verge," technology news website said. "Until we’re back, we’re reporting to you live out of Google Docs."

Several websites, including The New York Times, CNN and The Guardian, appeared to return online about an hour after they were temporarily disabled.
