sudden low spam levels?

Mon Jan 3 18:04:55 UTC 2011

I have two independent mailservers, and two other customers that run their own
servers, all largely unrelated infrastructures and target domains, suddenly
experiencing low levels of spam.

Total emails/day dropping from some 175,000-250,000ish to 50-75,000ish (legit
mail in the 2-5,000 per day, yes I have some high spam:legit customers...). 3
days in a row now at least, at quick glance.

Did someone set up them the bomb?
