We will be performing an urgent maintenance on Battle.net which may prevent players from logging into the system. Players who are currently logged in should be able to continue to play normally.

We expect this downtime to begin at 2:30 p.m. PST and end at approximately 4:30 p.m. PST. Thank you for your patience while we improve the Battle.net system.
