Facebook, Instagram, and WhatsApp are all experiencing issues this morning for users worldwide.
All three networks are not loading, showing instead a message that the site cannot be reached.
The issue is thought to be impacting both mobile and desktop users, as well as those attempting to access Facebook Messenger.
The three platforms are all owned by Facebook.
It is not too clear as to what the problem is, although many users have taken to Twitter to voice their frustration at the outage.
