Insane Lag

I haven't received any errors such as 90000 or 1017 when logging in (only being put in a queue for a short while, I play on Excalibur...), but when I do log in I get lag so bad it essentially renders the game unplayable, server info bar show crazy figures like Sending: 8 Receiving: 3500. Is this just a symptom of the issues so far? My only doubts are that most others don't seem to be suffering such lag as me. /worried
