I've been playing since Oct weekend betas and have only had one issue which was a BSOD that I am fairly sure was my computer's issue and not a server issue. I play on Shadowhand which is almost always full. I haven't heard any issues from anyone else in my guild related to server disconnects.
Guess we're all just lucky!
