I had this problem in the weekend and now again.
I've tried to log on about 7 times, ranging from 18:00 to 21:00, keep getting disconnects.
Usually I don't even bother since I've better things to do with my free time than keeping my fingers crossed.

Few times I managed to log on but than it disconnected me with in 2 minutes, or it just lagged out the moment I spoke to a NPC.
These problems are happening quite a lot.
I could easily say that 10 days of my sub have gone to waste because of the servers are not working.
That and well I can only play at the evening.

I'm getting a bit tired of it, and it feels like a waste of money.
