our bfbc2 server in Los Angeles had to be moved to a different box [in Los Angeles] and assigned a new ip. unfortunately this means its rank and other stats on tracking sites such as gametracker.com have been lost. i’m not happy about it but it was completely out of my control so moving on! 
if you added the server to your bfbc2 favorites before it was moved you can still connect to the new ip that way.
