We will be bringing down the Public Test Realm login services down for maintenance at approximately 6:00 AM PST on November 18, 2010. At this time, you will not be able to login to the Test Realms. Maintenance is expected 4 hours.

This thread will be updated as more information becomes available.

[Edit]
Corrected time

We are currently experiencing some issues with the login services for the PTR.

Maintenance will be extended until further notice.

Maintenance is now complete.
