Popular social media platforms, 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. By 17:24 BST over 50,000 people had reported issues.
The three social media services, all owned by Facebook, run on shared back-end infrastructure, and other Facebook-owned services are also down, including Facebook Workplace and the Oculus website.
There have been a number of social media outages in recent months, with Instagram going down for 16 hours just last month, and all Facebook platforms down in June.
Soon after the first report came through, the hashtag #facebookdown was trending on Twitter, with users worldwide reporting issues connecting.
On Twitter, Facebook communications executive, Andy Stone said they were aware some people were having trouble accessing Facebook apps and products.
‘We’re working to get things back to normal as quickly as possible, and we apologize for any inconvenience,’ the executive said in a tweet.
The various Facebook-owned platforms, including WhatsApp, Instagram and Facebook itself, took to Twitter to explain the issues and say they were working on a solution
The hashtag #instagramisdown and WhatsApp were both also trending on Twitter, with a number of users saying they checked their internet connection when they couldn’t get on Facebook.
Instagram comms tweeted: ‘Instagram and friends are having a little bit of a hard time right now, and you may be having issues using them. Bear with us, we’re on it!’
WhatsApp tweeted: ‘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!’
Even Oculus, the virtual reality gaming platform owned by Facebook was having problems, with one user describing their headset as being ‘like a paperweight’.
