Hey there you are not alone, while I was playing WOW on Christmas 25th of December my ping was around 220-230ms. Unfortunately, starting on 27th of December my ping became 500-510ms. Besides WOW, I do play Diablo 3 and Starcraft 2, both games lagged as well. Diablo 3 normally the ping will be 200ms, but since 27th of December, it turns into 500ms which is unplayable at all. I'm not sure whether this is Blizzard's issue or TMnet's issue.
