When I check using some tools like netstat, I'm seem to be connected to 199.91.189.22 (seems to be Phoenix EU);
Code:
TCP 192.168.1.100:54013 199.91.189.22:55029 ESTABLISHED
[ffxiv.exe]
TCP 192.168.1.100:54014 199.91.189.22:55029 ESTABLISHED

Location info on that IP: http://www.iplocation.net/?query=199.91.189.22

So if you live in Europe, don't really think it matters if you join EU or NA servers... Pretty sure the NA servers are also located in Canada.
I live in Holland and I get 100ms connection with Phoenix atm, is not bad...
