The social media giant stated that it's aware some people are "having trouble accessing the Facebook family of apps" and that it is now "working to resolve the issue as soon as possible".
It appears like similar problems could be causing Facebook's photo-sharing social network Instagram to be down too. "We're working to resolve the issue as soon as possible", a Facebook statement said on Twitter.
Facebook and associated apps and services like Instagram and Facebook Messenger seem to be experiencing issues and error codes preventing login.
It appears Oculus is also affected as some users have reported (via Verge) the feature for authenticating logins through Facebook is down.
The site has been hit with more than 2,700 reports of outages.
Third summit between Trump and North Korea's Kim likely, no date set
That does not, however, mean anyone is giving up, and both sides seem interested in finding new ways to approach diplomacy. So that's one reason why we pay particular attention to what North Korea is doing all the time.
Facebook makes more than $90 million a day in ad revenue, so any extended outage of its main advertising conduit adds up.
It is still yet unclear why two of biggest social media networks have just gone down out of the blue.
Some people are reporting a total blackout of service.
Facebook did not give an estimate for when they expect the problem to be resolved. "This isn't the first time an outage has occurred".
So of course, people are taking to Twitter for memes and mocking.
As it turns out, many people have experienced the same problems. I have still been unable to post anything, even though the social media site is accessible.
