Hey,

The following World of Warcraft realms are currently unstable due to technical issues:

Auchindoun
Ghostlands
Hellfire
Karazhan
Nagrand
Shattered Halls
Sporeggar
The Sha'tar

The issue is that these realms are sometimes shown as being offline, even though they are not. You will sometimes see it as offline, and sometimes as online.

We are working to resolve this as soon as possible and will keep you updated. Thank you for your understanding.
