I am having a similar issue as bogey, but I wanted to post here so it doesn't get mixed in.

I just tried to play and I can't even connect to TTP. I get the "Your connection to the server has been lost" immediately before the map even loads. Last night the map was loading and I would get dropped after 2-3 minutes.

I download a program called pingplotter and entered the servers IP.

This is what I get:

It seems that packets are getting dropped on the Dallas hops. Any help?
