They’re some of the most popular social media apps around the world, but it appears Facebook, Instagram, WhatsApp and Facebook Messenger have all crashed.

According to DownDetector, the issues started at around 16:44 BST (11:44 ET), and are affecting all users of the social platforms globally.

The three social media services, all owned by Facebook, run on a shared back end infrastructure, and other Facebook-owned services are also down, including Facebook Workplace and the Oculus website.

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.

Thanks for your patience!
