Logged out of Facebook? You're not alone and Facebook blames configuration change for logouts

"Why am I logged out of Facebook?" The question ricocheted around the internet as an untold number of people across the nation found themselves logged out of their apps Friday night.

If this happened to you, you are not alone.

Users flocked to Twitter with the hashtags #SoFacebook and #FacebookDown quickly becoming a top trending topic in the United States.

Facebook blamed a configuration change for logouts and confirmed to U.S. TODAY that some users were having problems.

"We're looking into reports that some people are currently having to login again to access their Facebook accounts," the company said in a statement to U.S. TODAY around 1:20 a.m. ET Saturday. "We believe this was due to a configuration change and we're working to get things back to normal as quickly as possible."

At 7:06 a.m. ET Saturday, Facebook posted an update on Twitter that said engineers "fixed the issue." However, some users responded to the tweet saying they still were unable to log in.

According to Downdetector.com, which tracks outages, thousands of users reported problems with Facebook Friday. Some users say they were able to log back in while others said they were waiting to receive a code from Facebook.

Among U.S. adults who use Facebook, nearly three-quarters visit the site at least once a day, Pew Research reported in 2019.
