Social media platforms Facebook, WhatsApp and Instagram are gradually coming back after an almost six hour global outage, Facebook says.
All three services are owned by Facebook Incorporated and could not be accessed over the web or on smartphone apps.
Downdetector, which tracks outages, described the situation as the largest failure it had ever witnessed, with 10.6 million problem reports around the world.
It was in 2019 that Facebook last had an outage of this nature.
In a tweet, Facebook rendered its apologies to those affected by the outage.
It will take some time for all social media platforms to be 100 percent efficient.
