Severe server lag

I joined the server tonight around 9:20 to find 11 players on ns_agora. The play count was very encouraging, but the lag was not. Everyone on the server had 650+ ping. Before I could change the map, several people dropped. We aren't going to have many players return to the server if these problems persist.

HCS, Plankeye: Could either of you tell me what might be causing these problems? I have my doubts that it's AMX Mod X, but I suppose it's possible. Could it be something else, perhaps?
