I'm just speculating like everyone else. It's difficult to extrapolate from a single person's nightmarish experience what the experience will be like for an unknown but large number of developers. I hope that gets sorted out quickly. From some other comments it sounds like they still have some bugs in their process.
Unless Microsoft is purposely being opaque with details of why something has failed for the purpose of thwarting malicious or wayward developers, then they should take this as a hint that they need to provide developers with more information so they can track down issues and fix them.
