Update Friday 9/04/2021 00:29: Facebook services appear to have recovered. WhatsApp, Messenger, Instagram and Facebook already work for most users and they don’t seem to be giving any more problems.
The Facebook ecosystem has fallen again after only a few weeks since the last time it happened. WhatsApp, Instagram, Facebook and other services of yours do not work correctly for many users globally. The company has not yet indicated what the reason for the problem is.
