Around six hours after Facebook, WhatsApp and Instagram went down, service started coming back online.
All three services are owned by Facebook and could not be accessed over the web or on smartphone apps.
Downdetector, which tracks outages, logged tens of thousands of outage reports for all three platforms around the world.
The last time Facebook had a disruption of this magnitude was in 2019.
As yet there has been no official reason given for the problem. But online network experts speculated it may involve an error with DNS, or the domain name system, for Facebook sites.
