No ETA sounds promissing...or not
No need to be so negative. They're looking into the problem. It's difficult to give ETAs for stuff like this (as anyone who's ever worked in the mechanical or tech industries could tell you).
Just relax. It'll be back up soon enough. Personally, I think it's a good
sign that they were very quick to respond that they were aware of the issue in many other threads, and that they made their own dedicated thread to post info during the fixing process.
