As Will said in an earlier post, it is a WoW problem. You are focusing on the fact that at 6PM it all goes to hell. Of course it does, the uncapped product is shaped, it was shaped before Blizzard changed the way traffic is handled in game. Unfortunately, that is most likely the main cause of our latency issues, as we know MWEB is shaping the hell out of P2P traffic.
Does this make it MWEBs problem though? Not quite. Their product hasn't changed, in fact they were implementing better shaping rules for gaming traffic when Blizzard dropped this on our laps. Despite Will's best efforts, we have to wait for Blizzard to come up with their solution instead of expecting ISPs (local and international ones, including Virgin Media and O2 which are huge) to shake up their entire network for a game. It sucks, but unfortunately there is no way for them to differentiate Blizz P2P and normal P2P.
