Nice while it lasts

Earlier this week, the Washington Post reported that McColo Corp., a San Jose, Calif., based Web hosting service responsible for hosting some of this world's most notorious spammers, had been shut down. As a result, the volume of spam dropped by over 60% during the past 3 weeks.

Perhaps you noticed... perhaps not.

Either way, no one expects the current lower levels to be permanent. McColo's clients have likely made arrangements

with other firms to participate in their ignominious ventures. Nevertheless, the graphs below show the amazing effect that this victory has had on spam traffic. Kudos to Internet Service Providers Global Crossing and Hurricane Electric for pulling the plug on McColo.
