Facebook appears to be suffering a major outage, with thousands of people in the UK claiming they are unable to access the social network.
According to Downdetector, which monitors online outages, 66% of users are reporting a "total blackout", with a further 23% claiming they are unable to log in.
The website's live outage map shows that the outage is affecting users in the UK and some other parts of Europe. The rest of the world appears to be unaffected.
Many users took to other social networks, including Twitter, to vent their frustration and share screenshots of their blank news feeds.
"Everything down for me at the moment," one user on the DownDetector site.
"Same here," wrote another. "Blank pages everywhere, no error messages in browser. Downloading page and CSS, but no content being fetched afterwards."
Facebook has been contacted for comment.
Instagram down?
Some people are reporting that Instagram, which is owned by Facebook, is also experiencing issues.
Again, the issues, appear to be confined to the UK and Europe, with the majority of users complaining about problems with their News feed.
However, the numbers in this case are much lower.
