Upgraded net speed hoping for improvement....

You could have the best internet on the planet, but if there's something wrong going on along the pipeline somewhere that doesn't really matter.

While I do understand that this can be a thing, the problem is, FFXIV is quite literally the only game i have this issue with and it doesn't matter what data center or server i check, they all have a poor connection when about a year ago they were excellent or good.
There are servers hosted in the same cities as the XIV servers which are fine. (Im not sure if they are hosted in the same server farms or not, doubt it somehow).

Its my understanding that a bit before the WoW player influx, there was an update too the game that ruined a lot of peoples connections out of nowhere and I haven't seen a fix listed for the problem, Happened while i was on a break so not sure if that's it or not but considering how consistent the bad Connection is across all Data centers I have access too, and the fact its only a FFXIV problem, that's the theory im leaning towards atm, Posts on that problem are starting to become difficult to find however when i went searching earlier too see if there has been a fix.

Called my ISP after making the first post on it here as well, they say there shouldn't be any issues between me and them and claim the problem is at SE's end. The 'pipeline' shows no sign of congestion but their tests have issue at the game server end.
