These pages contain some unsettling analysis of the effects of Microsoft worms like Code Red II and Nimda on global BGP routing instability. They've been significantly extended since last week, and we *strongly* invite the NANOG community to send us supporting data (or even anecdotes, let's be generous) from the propagation periods.
I read over it quickly, a lot of great data. One thing you may want to consider is the difference multi-hop BGP has in your data collection. For several years, router vendors give priority to locally sourced routing packets on local interfaces. But on multi-hop sessions, I believe that prioritization is lost which may show up as more instability than is actually present at the local BGP exchanges.
