We are aware of the issues currently affecting access to instances and battlegrounds on the Whirlwind battlegroup (http://www.worldofwarcraft.com/pvp/battlegrounds/battlegroups/), and are currently investigating. Here is a list of potentially affected realms:
Sisters of Elune
The Forgotten Coast
I'll provide updates here as they become available.
