My home business was down for hours from side effects of 1,
most of a day from side effects of 2, and didn't notice 3.

Current backbone engineers I talk to on a regular basis fall
about 50:50 into similar experience and having also taken
a hit Sept 26 AM when Backhoe Roundup began.

Speaking of which, this *has* been an interesting 2+a bit
week period; reflecting on the various effects sounds like
a good NANOG paper.

I'd disagree somewhat there.  I think it mostly affects things
the further from "backbones" that you get; a lot of ISPs took
severe hits across their entire network depending on the manner
in which IP space is allocated across their networks interacting
with the attack patterns of Nimda.  That doesn't map well to at
least some usage of "edge", but I think I get your point...
