Facebook users are reporting problems logging in Sunday, with many hitting a page titled Facebook Error.
The first reports of the Facebook Error started Saturday (US time) but escalated Sunday as more users hit the screen (per the pic above).
An unconfirmed report has Facebook grappling with issues relating to the Facebook worm, “resetting some user passwords and scrubbing the service for the malicious links,” the result of which may be related to the issues.
At the time of writing, Facebook is working for me, although users on Twitter are still reporting the Facebook Error message.
If anyone knows more, leave a comment.
