I live near Atlanta, GA USA (as my traceroute would suggest, being a network engineer though I'm sure you could tell) and use Comcast. I have their highest available speed home internet (which is pretty redonkulous) so as far as paying a premium, I'm already there. Again, nothing else triggers any form of filter on my ISP. "However FFXIV sends/receives the data it is tripping a filter with your ISP and you get the connection issues." Oh, sounds like a SE problem to me with how they handle data. I've tried many things, including no firewalls, DMZ, direct connection; nothing changes the issue.
