We're continuing to work through today's maintenance, which includes the implementation of the 2.3 content patch. While we originally planned for an extended maintenance, the features for the new patch look to require more time to implement and configure than originally anticipated. We're extending the current maintenance time by two hours, bringing the realms up at approximately 1:00pm PST. We thank you for your patience and hope to have the realms available, with the new patch and changes, as soon as possible.

Thank you,

Blizzard Entertainment
