Earlier this month spam giant McColo Corp. was at least partially taken offline. McColo is a Web hosting service that has been credited with enabling 75 percent of the world's e-mail spam and scams. It had been watched by security experts for years but is one of a handful of hosting services that authorities thought was "bulletproof".
McColo was disconnected by two of it's upstream peers.
MessageLabs reported "a massive drop in spam volume to levels eight times less than typical volumes."
