I have the same exact problem and it's ongoing again at this time. Had it first time on 7th of July which sorted by itself in 6 hours or so. Connection went back to normal and went out again yesterday for few hours. Came back and dropped off again just hour into playing.

I can't connect into the game and any Square Enix site is really sluggish to load (I'm amazed if I succeed posting this). I'm located in Finland, but what's funny there are some swedish LS mates of mine who don't have any problems with this. My connection too travels through loa.seabone.net as does the starter of this topic.

I assume SE can't really do anything about this 'cause the problem is somewhere in mid-Kansas?
