The big winner was AS 7788 MAGMA-COMM, which dropped from #3 to #147 by decreasing from millions to less than a thousand spam messages in the January 2013 for Canada. Magma had a brief spate of Kelihos spam in the middle of the month, but it only lasted less than a week. Almost as good was AS 6407 PRIMUS-AS6407, dropping from millions the previous month to a few hundred thousand, and from #6 to #11. That one while beating its Kelihos problem, seems to have developed a Cutwail problem, which was sending increasingly more spam at the end of the month. Since Magma was bought by Primus in 2004, Primus gets double congratulations!
