Not blizzard specifically, more Activision-blizzard, but the latest call of duty open beta was reportedly running on vultr for at least some of the game servers. I think they moved it back to in-house servers when it went live, though, and dropped the server rates from 60hz to 20hz. Kind of a shame, the difference was very noticeable.
