How should those of us receiving the 401/601 errors proceed?

I can tell you what not to do. Dont contact costumer support. Cause they are completely useless. I just wasted 4 hours in line. All they did was coming up with excuse as how all this is on your end, and not theirs. Sad how they dont even wanna help people out, when they are trying to give them money..

4 hours? I thought I had it bad with 2 and a half just to get a copy/paste before they left.

So far the only work around that seems to work for people are those ultimate gaming cards. It sucks, but it's a temporary solution until SE figures out what's going on.
