Can't log in, stuck at "Connecting.."

After stuck at connecting for hours of tries, I manage to log in , get in-game for 2 minutes of 8k latency and then it disconnects me and the story repeats. I was playing on the same connection months ago and I didn't had any problem and now when I play WoW again I get this problem... Can at least a staff member come and say if it's from us or them ? So we can stop trying doing all things to our game... I saw 1000 posts about this, not even 1 reply from a staff member...

Thank you!
