I've been having similar issues myself despite using a VPN. I thought that raising my ping from a low number to 100 was supposed to make the "servers more stable". It's not only irresponsible for SE to go and stack their servers, on one extremity of the continent, but we still see similar issues as before the move plaguing the game. I've been having issues with some San Jose node, very close to Square Enix, and that node drops packets like crazy.

This is the only online game that I play where paying extra money for a VPN is almost mandatory, that's how bad the connection/game servers are.
