Congratulations to Turkey's TTNET's AS 9121 for getting Festi botnet spam down from more than a million messages a day to less than 100,000!
However, Festi is still in there, and TTNET has other problems, as well, including Lethic, Cutwail, Waledac, Maazben, and even Grum(!) botnets, plus Sendsafe.

TTNET still has room for improvement. How will TTNET rank in the August SpamRankings.net? Stay tuned....
