All i know is that I've not had a single problem with playing FF14 on PS3->PS4 for the entire duration of its existence since the initial launch, and now all of a sudden i'm having the same issues as many other EU residents playing on NA servers and getting constantly disconnected all of a sudden. I'm not entirely sure what the problem here IS, but what i can tell you it ISN'T is the fact i'm playing on a PS4, the fact there's never been any prior issues, and suddenly everyone is having issues all at the same time leads me to believe it's a problem over at Square enix or with Sony itself rather than the ability of a playstation console.
