What issues are you talking about?
Every major patch the servers have issues. It has nothing to do with there location.
Also they are in Canada because SE has a studio in Quebec, for that reason they wouldn't move to Texas or Chicago.
I'm on Balmung, I haven't noticed any issues.. playing 2-4 hours a day. Sure they keep doing maintenance but I understand that as a dev post a patch and it never overlaps my playtime.
