CoD4: taking a long time to find a game in the lobby

Yeah, I went back to CoD4. I hate CoD:WaW. So what, you wanna fight
about it? :)

Starting about a week ago, it suddenly went from finding a game right
away, to sometimes taking 15 minutes.

As far as I know, my NAT is okay. If I test my connectino, I don't
get any error messages, so I assume my NAT is open.

Wasn't there a place to actually check that before the New Experience?

Anyway, do you think I have a network issue, or it's just a matter of
not as many people playing anymore?
