Network issue, no amount of hacks, DNS, HTC_CM etc etc change will NOT work.
Given you live near the east coast NY,VA,PA,MD,DE,CN,Mass etc, you must call *2 no if and or buts call now.

Say that, your call will get added to the issues' Ticket#, we'll need at least 50 calls for the ticket, it went up yesterday.
