We saw a dramatic decrease. Attached is our dnsbl mirror in .ie, it mirrors spamhaus amoungst other things.
The numbers are in 1000s of 1000s per 5 minute window. (so 2500k = 2.5m) You can see a dramatic decrease that corresponds with them going offline and then the spam level gradually coming back, but it's certainly not back full tilt yet.

It's interesting that each service provider's spam populations are as different as they are. Some experienced gigantic decreases, others didn't. And it's not like we have just one domain. I know MessageLabs examines spam rates per industry type.

I know major operators who have claimed to see a gigantic decrease.
