Another problem in World of Warcraft Realm is on logging into some of the realms. Blizzards or the developer is aware of the WOW problem and they are trying to fix it as soon as possible. A vast amount of WOW players were affected and still not able to login to their server of choice.
To know the status of the realm that were still down or not, you can check the World of Warcraft Realm Status page.
