I'm glad you bought your own servers.

kod is on individual clients. Ie if a single client starts hitting too
often in a time period a KOD is sent out. It does not care if 1000000
others are hitting. Mind you if 100000 are hitting at about the same time,
the internal tables cannot keept track of that many clients, and I doubt a
KOD would ever be sent out.

I do hope you are not hitting with each client once per second or
