50 ping.
I quit the server when I tried, unsuccessfully, to hit a shadowcat who was within maybe 50 meters of me.
I would line up, pull the trigger, then he would disappear and would be behind me.
Then i would explode, even though I had no visible damage before exploding.
I had been having trouble hitting people all night with heavy gaus because of warping, but when it became impossible to hit people at a few meters that's when it was out of hand.
I think people with greater than 200 ping should be auto kicked, and the server size reduced to 24, this seems to be manageable on other servers (such as TLL, Fed Suns).
EDIT: No I am not a Euro, I live in the midwest US.
