Another person who clearly doesn't get it. Do you really think Blizzard is just sitting back going ''hey I wonder how long this will take?" You just can't flip a switch to end a DDoS attack, its not something that is simply just fixed within minutes. You have to find where the attack(s) are coming from block them, reroute traffic, re-assign new I.P.s so the others aren't targetted anymore.
Go the fuck outside for awhile and get over it.
