Lag, 90k, 2102, other error codes

[Flapjack]

I've had 5x 90k errors today in 3 hours of playing. I've also had large lag spikes where the game (monsters and/or FC chat) "fast forwards". I have seen the problem in non-instanced areas (Quarrymill) and people in my FC are reporting it within DF instances.

I've had zero problems with the game until this point but something changed after the maintenance on 05/15.

EDIT: Just got a Lobby Server 2002 error. All other streaming services are working fine. Comcast/Xfinity is my provider.
