Latest Data from Google on Spam Volume, Back to 94% of All Email

While Google's security and archiving team says they are not certain how spam volume has already risen back to its pre-McColo levels, "data suggests they're adopting new strategies to avoid a McColo-type takedown from occurring again."

Amanda Kleha, a member of Google's security and archiving team writes: "The most significant spam-related event in the first quarter of 2009 occurred when spam volume returned to pre-McColo takedown levels. By the second half of March, seven-day average spam volume was at the same volume we saw prior to the blocking of the McColo ISP in November 2008. Spammers have clearly rallied following the McColo takedown, and overall spam volume growth during Q1 2009 was the strongest it's been since early 2008, increasing an average of 1.2% per day.
