huh weird. It seems to have gone away after about an hour or so. Nevermind! Anyone know the reason behind this/how to prevent it in the future?

Hi my roommate and I were playing earlier with some other friends and all of a sudden we couldn't log back in. The FAF client would say "unable to connect to server" and we weren't able to access the forums.
We are assuming it is a IP ban of some kind? Is there any way to appeal the ban/tell if it is actually a ban?
We didn't get any email or any other sort of notification.
Thanks
