This is pretty much what I figured. I didn’t expect that a “normal” DDoS protection/mitigation service would work well for Blizzard specifically, just mentioning that they exist.

Is there anything that indicates this beyond Blizzard’s posts? I mean, there was no indication of west-coast internet issues at the time, just B.Net being down.
