You may be dropped into a match on a European server, for example, automatically afflicting you with near game-breaking lag.
Oh delicious irony.
The reverse of this phenomenon is the bane of most European IWnet user's lives, it's nice (for us) to see the reverse inflicted, even if it's not deliberate.
Although perhaps it is deliberate, Dice being Swedish, maybe it's a quiet subtle jab at all the Americans who insist IWnet has no lag problems. A slient, unannounced trap to force you all into the agony of matchmaking deciding the best connection for you is a 600pinger... I'm going to get my tinfoil hat...
