I had a few problems early after release, but then it was fine until a week and a half ago Friday. Since then, I can rarely log in for more than a few seconds, though I do sometimes get an hour or two before 90000. The problem is clearly a routing issue from the server so there is nothing any user can do other than switch ISP / use a VPN in the hopes that the routing is adequate. Not being willing to pay even more for the game, I'll give it a week or so, then give up once and for all.
