At the time of writing, Facebook services worldwide are being disrupted, causing users of Facebook, Messenger, WhatsApp, and Instagram to either give errors preventing them from posting anything or downright not working. The problem first originated in Europe but has spread across multiple regions across the world.

Many users from the United Kingdom and many users from Europe have reported the same issue. But that is not all; Portugal, Romania, the Middle East, India, and some parts of South Asia have also reported the same problem. There is certainly something up, and it has been almost 2 hours since these services have gone down. But the issue is not affecting all the users, and some of them can still access and use these services, while others cannot.
