It's called "Not accepting players." The server is soon about to get open. It's still starting everything but checking if everything is ok. It's normal. Most game servers do that. I agree on making an option like "Locked" on the server list at the launchpad. Went looking twice because I didn't trust it.
Ah, okay; I knew of this update, but I thought it was already done sind I live in Germany, GMT+1. Can you tell me how long the update will take from now?
