Did your Twitter app suddenly give you the boot or otherwise behave strangely? It's not just you. The social network has confirmed a sign-in problem that's kicking out hordes of users (so far, mostly on Android) and preventing them from logging back in. Also, TweetDeck on the desktop is listing every new tweet as a year old. We've reached out to the company for more details, but it's possible that there's a date-related flaw at work -- a coder who intercepted the Android app's login traffic, Ninji, has noticed that the company's servers believe it's already 2015. Twitter has engineers tackling the issue, so sit tight if you want to tweet through your favorite apps.

Update: And we're back.
