Major Spammer Haven Shut Down: Spam Volumes Drop by Two-Thirds

The Washington Posts's Security Fix blog reports that spam volumes declined by 2/3 after an ISP that was hosting spam operations was taken offline. The story:

The volume of junk e-mail sent worldwide plummeted on Tuesday after a Web hosting firm identified by the computer security community as a major host of organizations engaged in spam activity was taken offline. Experts say the precipitous drop-off in spam comes from Internet providers unplugging McColo Corp., a hosting provider in Northern California that was the home base for machines responsible for coordinating the sending of roughly 75 percent of all spam each day.

Further details are available from here and here. Hopefully, this means less work for all of our organizations when managing junk email through our hosts.
