I've been getting hit with the same error codes all day long, without any issues of lag. Just instant disconnects every 10-30 minutes with a 90k error or 3102 error either when I'm booted out of the game or trying to reconnect to my character. Connection strength also keeps varying between Excellent or Poor on reconnects.
Thought it might have been an issue with my ISP since my modem had issues getting a signal for about 8 hours before I started playing, but seeing that other people have been having similar troubles today, I'm starting to have my doubts about that being the case.
