Ragnaros have the same issue
Same Here, me and and a friend in the same time
I can enter the game from all servers with my characters. but it does not appear on the twisted nether server where my main character is and I cannot enter the game.
Same here 
yeah I have it same problem I was in ravendreth then my game was down btw I cannot see my characters well itâs only dark I can see.
Wtf is going on, nothing works as it should⌠Looking for blue post!
can not connect to blizzard app either, TN seems dead.
World server is crashing constantly
Iâm so pissed, i was trading a weapon with a paladin after we killed HC Sire, and the trade was canceled over and over even after we both agree⌠We said âlets meet at orgrimarâ, I used HS and didnt get tp, I used Dalaran HS and got logged off, now i cant log in to trade himâŚ
Managed to log back but everything is lagged outâŚ
I have it too
Blue not showed up still?
I think we should cry more to get attention 
Same here aswell ! Can we get some answers?
Same problem all⌠30 min a problem
Same problem around 30 minutes now, was in a dungeon and bugged then on relog canât log in to the realm
Problem is back to me
Twisting offline
Characters show up after a min or so. After 20 attempts i managed to log in, but after the next loading screen it got stuck againâŚ
Think Ragnaros-EU is affected as well
Same with ragnaros, cant see my chars, other reams works, tried the unstuck button and the realm doesent appear
