During the Beta Weekend, the servers will be running from Thursday 7PM CET to 10AM on Monday morning. So there's plenty of time to get your shifts in!
The game will automatically choose the server which you have the lowest ping to, however in the case of long wait times you can also jump to different servers from the Menu (press Esc in-game).
Please note that the matchmaking is server specific, so if you are having issues finding a match, try out another server! However, there is a known issue that the server selection refreshes to the one with the lowest ping after every match, so you might need to reselect the server you want from the list.
