@Dana Myself and another player were booted from Test Client PVE-NA. Neither of us can connect to the server even after rebooting our computers, but I can connect to PVE-EU Test Server.
I was on the server with a clan mate when it crashed. Tried to rejoin and got the can’t join server message. Now the server is no longer listed at all.
@Dana The server is still not listed this morning. The other 3 are listed: PVE EU, PVP EU, and PVP NA… but not PVE NA.
What’s going on?
I believe the servers have been taken down as we are currently releasing 2.2.0 on the live client.
The Public Beta servers will be back up once we have a new update released on that specific client (The Public Beta Client)
I was playing on the PVE-EU this morning. EDIT: I just logged in again unless they will be brought down when the Live servers are updated.
Will check with the team 
All the Beta servers should be unavailable now.
Thank you all for helping us test this update. The team is now collecting all the player IDs and they will distribute the Golden Pickaxe soon 
Will they come back, or are you wiping them???
They will come back the way we left them.
Is that the usual pattern with their beta server? Hate to lose all the work put in.
Way back a long time ago, they would leave the test servers up all the time. More recently, they usually leave them up for about 10 to 14 days in between updates. They will be down for a few weeks at a minimum. Did you see my message to you?
Yes. So when they eventually come back at some point, it will be where we left off? We were in a middle of a fight with our high level thralls at the time.
Yes, your progress will stay on the server so you will be able to continue once servers are back up.
The servers will be back once the next update is ready to be tested by all of you 
Thanks for the info -
Do you have a rough estimate on when that will be… Weeks.. months??
