Quick announcment from Mr. Conway on the EU forums:
Commanders,
We will be running a test for the new Advances mode that is being introduced as part of our Renewed Strongholdsthis evening and would love for as many clans as possible to participate.
- Read our Advances guide to find out how to play the new mode.
- It will only be possible to play one round of Advances this evening
- In order to participate you need to have your Detachment ready and push the battle button before 21:00 CET
Good luck and have fun! 
So is that EU server only?
Exactly yet another shit post with missing information needed by the community.
Set test for 21:00 when CW is played, ask for as many clans as possible to participate.
