nah, you wont get connected to those servers, the game will choose servers closer to you..
like i said, im on the west coast, and i have a filter around the UK and never once have i connected to those severs when gaming..
the reason why i think theres an authentication sever there is due to the fact that when i connect to a west coast server, itll show it pinging to the UK as well(but not actually putting me on servers there) its a bit hard to explain..
also, are you on the R3? if so, if enable steady ping and try severs like Georgia, and florida as well... just increase your filter radius or add a filter around both Georgia and florida as well as the filter you currently have...
