I am also having problems with 90000 disconnections in crowded zones. The lag is also pretty bad if I try to do any actions or group up for hunts. Checking retainers is impossible as is doing anything in towns. This only started this week, however a friend also on the server was encountering problems ever since the maintenance. Before this we had no problems with lag.

I've done a trace and found the problem to be large packet losses from the 66.198.123.25 server that my packets are routed through.

I am on the Diabolos Server and am using Time Warner Cable. Everything else I am connected to is fine.
