Update 8:15 p.m. PST

The DDoS attacks continue. Blizzard is rolling out updates to the backend services at a breakneck pace right now, some of which are having unintended consequences and further complicating an already messy situation. However, it should be noted that this is to be expected when combating such a large scale attack. In no way is Blizzard responsible for the server outages on this scale — responsibility rests with the script kiddies and bot net controllers.

It’s hard to know just how big this attack is, but with the sustained issues it’s causing, and the severity of response from Blizzard, it’s safe to assume that it’s big. Battle.net is a hardened internet service that has withstood onslaughts like this before. For it to fail at such a critical juncture is nothing but catastrophic for the short term, and could have serious long term implications. We have some idea, shown above, of just how global this attack is.

We’ll update this post as the night continues, providing you with the latest. In the mean time — we recommend you catch up on your lore, and not concern yourself with logging in.

Original Post:

WoW Insider received reports earlier today that Blizzard may be the target of a significant DDoS effort — and community manager Bashiok has confirmed it on the World of Warcraft forums.

Bashiok goes on to outline additional issues Blizzard is currently attempting to resolve: instance servers timing out, disconnects from the continent servers, and performance and phasing issues with garrisons.
