After some network and machine outages, I currently rent more than one vps to get some fault tolerance for my botnet detection system. Sometimes one of them will serve as my test server, and data collected on that server might not get included in the daily statistics. I include their data when calculating the monthly statistics, so the monthly number of blocked spams and recipient count might be more than the sum from daily statistcis. Just in case you ask.
detection period: 2010-09-01 00:00 - 2010-09-30 23:59 UTC
total number of suspected botnet IPs: 56714
number of blocked spams: 13056115
recipient count of blocked spams: 421289111
