I from the land downunder. I'm being put into USA lobbies non-stop. The fact that in-game is showing me as a moderate NAT makes me think the servers are wonky at the moment. Here's hoping this will be rectified soon. I'm sure IW are aware of whats going on -I've certainly left them some notes.
btw - it is always expected that there will be wonkiness after title update releases - hence, I'm not kicking up too much of a fuss yet.
