Facebook and Instagram is down for several users across the globe for 8 hours.
A message showing to those affected suggests the problem is part of scheduled maintenance. Facebook's own developer page, however, makes no reference to those issues. "Facebook will be back soon," the message showing to users reads.
As the global outage continued, Twitter soon filled up with memes and jokes about the websites not working, and the hashtags #Instagramdown and #Facebookdown started trending.
