Effect of McColo takedown on spam volumes, from SpamCop.

McColo was a US-based web hosting service provider[2] that was, for a long time, the source of the majority of spam-sending activities for the entire world.[3] In late 2008, the company was shut down by two upstream providers, Global Crossing and Hurricane Electric, because a significant amount of malware and botnets had been trafficking from the McColo servers.[2]
