Examining the list of servers in the folder :
English Forums -> Community >Worlds (Group NA/EU), the server Zodiark lacks the (EU) showing that it is in the EU data center. This is also the case in the French and the German forums.
As Zodiark is the smallest server in terms of posts from the server - it needs all the help that it can get.
As for me - I'm on Mateus - the smallest server in the North American data center!
