Diablo 3 Update:
Its still broken as of tonight. Latency fluctuates between 260ms and 550ms and the game is very frustrating to play due to the rubber-banding effect. When I switch to my FNB Connect account, my latency is a consistent 206ms; honestly it doesn't budge by more than 5-10ms through the evening.
AfriMan, you asked for a tracert, but I don't think it is of much use here since the actual game server that I am connected to (as reported by my router) is ICMP blocked. Nevertheless, here is a tracert as far as it will get.
Code:
$ tracert 80.239.209.66

Nothing out of the ordinary there, in fact, it's good. I'm not sure what other evidence I can provide here, so all I can hope is that others can also put their two cents in and we sort this out asap.
