Well, I don't think there's a real West Coast vs East Coast time split here (pretty sure everyone just joined whatever server they wanted to). I have been seeing a lot of people talking about some servers being located in EU, though, which is interesting.

Pretty interested in that list, myself, though more for curiosity's sake than anything else.


Going by the server pings on the status website (http://www.arrstatus.com/), I'd guess that these servers have the highest probability of being in Europe:

Cactuar
Coeurl
Faerie
Lamia
Malboro
Midgardsormr
Siren


After checking a few times, only their pings stayed above 100ms (ignoring JP servers), so make of it what you will.
