Facebook logging to my account from a local IP address?

10.49.82.25 is a non-routable IP [1] -- meaning this is on their [facebook's] internal network. So, I would report this to Facebook, as some internal system has gone off the rails. Facebook can trace this IP back to an internal set of machines, and figure out what is going on. This is most likely a bug or something. Looks like you can probably report something here [2]. I would mention the bit about 10.49.82.25 being a non-routable IP and that an internal system is doing something wrong.

Chat was blocked in Pidgin and "chat.facebook.com" sent me an instant message that I should login on the website. Doing that, I got this screen.

What do you think, did Facebook get hacked? Twitter said that they suspected more websites to notice they got hacked.

Or would it simply be a bug?

Or is an employee logging into my account for some reason? I wouldn't know why though, I guess they would have access without triggering a login event.

Edit: The exact message was this: (11:22:25 PM) chat.facebook.com: Your account is temporarily unavailable. Regain access by logging into your account from your computer's web browser: http://www.facebook.com/

I had the same problem today around the same time (http://imgur.com/P7wUmro). Why would a local address be used?

Edit: I also use Pidgin, think that could be it?
