WhatsApp, Instagram and Facebook have all gone down in a major outage.

The three apps – which are all owned by Facebook, and run on shared infrastructure – all completely stopped working shortly before 5AM.

Other products that are part of the same family of apps, such as Facebook Workplace, also stopped working.

Visitors to the Facebook website simply saw an error page or a message that their browser could not connect. The WhatsApp and Instagram apps continued to work, but did not show new content, including any messages sent or received during the problems.

A company spokesperson said that it apologised for the problem but gave no indication of why the outage began or how long it might take to fix.

“We’re aware that some people are having trouble accessing our apps and products,” spokesperson Andy Stone said on Twitter. “We’re working to get things back to normal as quickly as possible, and we apologize for any inconvenience.”

The same statement was posted shortly after on the official Facebook Twitter page.

Instagram also shared a similar update.

“Instagram and friends are having a little bit of a hard time right now, and you may be having issues using them,” it wrote on its communications page. “Bear with us, we’re on it!”

And WhatsApp also updated users through its official Twitter account.

“We’re aware that some people are experiencing issues with WhatsApp at the moment. We’re working to get things back to normal and will send an update here as soon as possible,” it said.

“Thanks for your patience!”
