If you are a member of KGS and you encounter server lags - please note:
The default config. for "host" is "goserver.igoweb.org" change it to "69.93.74.2". In case the ip changes for some reason, you need to ping goserver.igoweb.org to get the revised ip)
It works for my case. I can play 10-sec Blitz now. Please tell your friends if you find it useful
