I hit the order button right when they became available. For about 25-30 minutes I was stuck with the error, but I retained my position in the queue despite the problems when giving my shipping details. After that succeeded I could pay (from what I hear you don't pay right away if you get one from a later batch). 
While the Index was in my cart the shipping estimate remained at 2 weeks, right after completing my purchase it updated to 7-9 weeks.
