Blizzard addresses Warlords of Draenor server problems
Server issues caused by large number of players in specific zones, and a DDOS attack.
The launch of World of Warcraft expansion Warlords of Draenor has been plagued by server issues, which Blizzard has addressed a few days ago. Writing on the World of Warcraft forums, community manager Micah "Bashiok" Whiple provided an update on server issues which have surfaced "due to the sheer number of players attempting to enter Draenor from a single location." The post also states that Blizzard "ran into a few other issues, including a distributed denial of service attack, that resulted in increased latency."
In response to the problems Blizzard has temporarily lowered maximum realm populations, which has resulted in higher queue times on high population realms. "Our current biggest hurdle is the concentration of players in specific areas and zones, and an unexpected effect of that concentration on the realm stability... Work is progressing on improving realm stability through fixes targeting individual in-game issues, as well as on the backend game and network services."
