I read a story about an attack on several root DNS servers recently -- maybe the same botnet was pushing a lot of spam, and got taken offline for one reason or another?

...that was when I saw a sudden drop in the level of spam attempting to connect to my mail server. It had been steady at about 50,000/day and then quite suddenly dropped by half. It's not as if it had previously been coming from a small range of addresses either, but there is a marked drop in the positive responses from RBL lists. I'm guessing that a big botnet controller somewhere has been taken offline. Would that be a valid assessment.
