How is this even possible? Ping related.

Lert: It isn't just a PC you pick up drive around in a car and plug in somewhere else. A WoT 'server' is a whole server park.   As for your problem, I too connect from mainland europe and have found no problem with USE server. I still connect with ~120 ping, as I did 3 months ago, as I always have. USW server I get ~200 ping, same as always.   Can you run a trace route to the NA servers? See at which hops the additional ping happens?
