Hello,
Your account is currently unsuspended but earlier today, you were suspended for High Resource Usage, which is different from bandwidth. Out of my time here, I have never seen a bandwidth suspension because it is advertised to be unmetered. The bandwidth on your account is as high as can be for the server you are currently on. It is not unlimited, however, because servers will always have their limitations. (we advertise our bandwidth as unmetered, not unlimited)
