Just an update for those afflicted by this issue.
A friend of mine is currently also affected by this, but can't post the information due to the fact that he can't login.
I'm posting on his behalf:

There is a problem on the other end with 02/BE, nothing really to do with SE or us. Basically have to wait until Monday for an update to the issue. Details are in the links provided:
