I'm also getting this issue. I could play for about 3-4 days after launch with only 1017 login issue but now I get error 90000 on my server (Marlboro) about every 20-30 minutes. I also experience lag spikes throughout my time logged on since the 90000 started cropping up.

Here is a speed test: http://www.speedtest.net/my-result/2945100729
And a ping test: http://www.pingtest.net/result/85968527.png

To show that I have a stable internet connection, any insight to this problem would be much appreciated.

Thank you!
