Blizzard has provided an update regarding Diablo IV's Beta server and queue status! In a forum post, Global Community Development Director PezRadar said that the team is working on a full fix for the disconnection issues.
Hi everyone Just wanted to provide an update regarding the queues players are experiencing this morning. The team is working through some issues behind the scenes that have been affecting players and causing them to be disconnected from the servers.
For the time being, we are managing the rate of players entering the game until we have a full fix for the disconnection issues.
This is done so we can ensure stability amongst players who get into the game after the queue process. If you are in queue, we ask that you stay in queue to ensure you do not reset your timer.Read more on wowhead.com
