Well for some, including me, Facebook is down and all they're saying is that it's due to maintenance but won't specify what maintenance they're doing.
This usually means we're making an improvement to the database your account is stored on. While this process won't affect your account, you temporarily won't be able to access the site.

For some of us, Facebook will still work as normal as they say they don't do maintenance on all accounts at once.
However, if you're already logged into Facebook, you should still be able to use it if your account is affected, however, if you try to log out and back in again, you may be one that's affected and not be able to access your account.Keep in mind, we don't do site maintenance on all accounts at the same time. It's possible that your friends will be able to access the site while your account is still unavailable.
