06:15:11 Link LoginServer Succeed.
06:15:14 Login LoginServer Success.
06:15:14 上次登录服务器[02]
06:15:14 服务器[02]当前在线率:27.46%,能否登陆:能
06:15:16 Link GameServer Succeed.
06:15:16 ->Login GameServer Fail.
the funiest thing is the server online rate drop greatly from 56% to 27% LOL
i'm wondering the other 29% are BOTs?
is there any way to detect login server IPs? or maybe the login server port?
