Facebook, Instagram and Messenger users have reported suddenly getting logged out from their accounts today (5 March) at 9:21pm.
"Facebook is down for required maintenance right now, but you should be able to get back on within a few minutes," Facebook shows when someone tries to log back in.
Once users try to log into their accounts, a message pops up, saying "session expired, please log in again".
According to Downdetector, the problem is global.
"Both mobile and Website are logged out and I can't get change my password. I thought I got hacked," a user wrote in Downdetector's comment feed.
