I'm having the same issues. Here's my data. I hope this can be resolved quickly.

1. – Windows 7 64bit
2. - Microsoft Security Essentials
3. – Cox Communications
2) - R0 with complete freeze and very rare disconnect to 30002 Error.
3) - very rare 30002 error.
4) - Occurs in every zone, but seems to be less prevalent in the early hours EST. Peaks around 8pm EST-2am EST
5) - Occurs sporadically in crafting, occurs predominantly when in combat.
6) - Occurs solo as well as in a party.
7) - Between several dozen, and none. Totally unplayable in crowded areas.
8) - I'm able to log back in after a disconnect within 1-2 minutes, but never immediately afterward.
