Most affected users reported a "total blackout", reporting that they were unable to log in to their accounts or the site would not load, The Independent reported.
According to DownDetector, Facebook had some issues since 9:12 AM EDT.
"Earlier today, a technical issue caused some people to have trouble accessing Facebook services".
Saturday morning turned out to be social-media-free for a number of Facebook and Instagram users, albeit involuntarily.
The issues appear to be affecting Instagram as well.
Users are also reporting problems with Instagram, Messenger, Tinder, and Pokemon Go.
Meanwhile, some Twitter users chose to have some fun with the outage. Facebook was back up in the Los Angeles area shortly after 7 a.m.
"Aaaargh both Instagram and Facebook are down!, wrote one woman. Facebook is down for maintenance right now, but you should be able to get on within a few hours". Let us know by posting your comments in the box below.
