Did our spam plummet with the earthquake in Asia?

Just checked out this article (hat tip to John R. Levine... I hope I'm using that term correctly otherwise I'll look quite the fool) about the earthquake in Asia knocking down spam volumes.  As an anti-spam fighter at Microsoft I can confirm that the overall level of volume is down substantially on Dec 27 as compared to Dec 26.  It's possible that our logs haven't updated yet but for the time being, looks like the anti-spammers have gained a bit of an edge.
