Global users are experiencing outages on Facebook, including all social networks the company owns, which include Messenger, Instagram and WhatsApp. When navigating to these websites, a server error will appear — Instagram shows a “5xx server error,” which indicates that this is an issue with Facebook’s servers. Users are also unable to send messages or load new content on the mobile apps for these platforms. Even Oculus, Facebook’s virtual reality platform, and Workplace, its business communication tool, are down.
