Having a little Facebook problem

So, when I try and log into Facebook today, I get the helpful message:

Account Unavailable

Your account is temporarily unavailable due to site maintenance. It should be available again within a few hours. We apologize for the inconvenience.

However, it has now been several hours. I've gone online and taken the advice – flushed the cache and cookies, rebooted the router, but still no joy.

Friends tell me that although the account is there, all its posts and friends seem to have vanished, which is not entirely comforting. The separate Michael Scott page is still available.

However, I will continue on Twitter.
