There's obviously some technical issues with Ping with the recently transitioned NA central server.
Just a suggestion; but as the entirety of EVE Online (except China) plays on a single server it might be worthwhile to rent some space on the Icelandic server as it works pretty well and it can be reinforced for high activity. They can handle tens of thousands of discrete commands, track missiles, shots, messages, movement all at once. Node matchmaking is much easier in WoT as they're only a few vehicles on each side rather than thousands.
Just a thought...
