Maintenance on our European realms has continued for two hours, with hardware upgrades proceeding as planned. In North America and Oceania, we’ve been making adjustments to realms settings in order to improve performance and stability.
Regarding gameplay issues, we continue to deploy hotfixes to the game. Our Customer Support team is updating known issues threads here.

Our Europe maintenance has been underway for an hour, with progress being made to upgrade that region’s hardware. In North America, we’re continuing to test the phasing tech that may allow us to expand capacity by a significant amount on busy realms.
We continue to deploy hotfixes to address a number of issues. You can take a look at many of these hotfixes in this blog post, but please note that we will not be posting updates to the blog overnight.
We appreciate your continued patience. If you're a Twitter user, you can follow @BlizzardCS and @Warcraft for updates. We will continue to provide regular updates here throughout the night.
Update 8:06 p.m. PST
We’re beginning work on the Europe hardware upgrades now that realms have been brought down for maintenance. In addition we’re pushing out code hotfixes we’ve been testing to the Americas and Oceanic realms, and we’ll be applying those same fixes to Europe realms during their maintenance. We’ll continue providing regular updates, but please be aware that most of our efforts are now focused on the Europe and Americas/Oceanic hardware upgrades.

Update 7:07 p.m. PST
We’re making preparations for the Europe maintenance beginning in just an hour, and along with hardware upgrades we will be implementing some of the performance improvements we’ve been testing. One of these is a fairly large change to the way the game world is run by the servers—expanding the phasing tech used for the Tanaan intro experience to the entire continent of Draenor. This will allow us to run multiple copies of Draenor simultaneously, spreading out server population, while attempting to keep guilds and parties within the same copy. We’re currently running tests of this tech on a few North American realms, and have found we’re able to raise realm capacity by a significant amount. We’ll continue to provide updates as we progress through the Europe maintenance, and prepare to apply the same changes on the Americas and Oceanic realms.

Update 6:00 p.m. PST
We’re continuing to work on improving realm and login stability, reducing Character Not Found errors, and hotfixing in-game issues. We’re making progress ahead of maintenance on a couple performance improvements, and we’re in the process of testing those improvements now on a few realms. Maintenance is beginning for our Europe realms in just a couple hours, and we’ll continue providing regular updates here throughout the night.
