If you were having a hard time connecting to Blizzard's World of Warcraft Tournament Realm, it's because the servers were recently shut down for some urgent maintenance. You shouldn't have any problems with it now though since the realm is up and running

Community Manager Bornakk has announced that they will be providing updates in case any more issues come up. Unfortunately, he failed to give any details on the specific problems which prompted the developers to shut down the realms. Furthermore, Bornakk's post seems to hint that users may still encounter a few more problems while accessing the realm.

We're going to be keeping an eye out for any updates regarding this issue, still, we're hoping that whatever caused the developers to take down the realms has already been resolved so WoW players can play without any interruptions.
