facebook having problems with downtime?

so my facebook account has been down since I woke up this morning – its now lunchtime and I still cant get in. No response from facebook themselves. First I got an error saying there was maintenace going on and now it doesn’t recognise my username and password. Even more worryingly inside facebook you cannot even find me! 😮

update: turns out no one here in the office can access it either.. wonder if its uk wide?
