[NANOG has been bouncing my attempts to reply to this thread 
 for several days, possibly because I quoted the word "u n st a b l e" 
 early on, apparently triggering the "un subs cribe" filter for words 
 that start with "uns" and contain a "b"..   If your posts to NANOG have 
 been silently bounced in the past, and your network's operational 
 issues lead you to start your posts with words like "uns tab le" or 
 "uns ol vable" or "uns uit able" or "u nsp eak able,"  wonder no more. ]

Anyone interested in this might also like to look at our report 
titled "Internet Routing Behavior on 9/11 and in the Following Weeks." 

 http://www.renesys.com/projects/reports/renesys-030502-NRC-911.pdf

Note in particular the minute-by-minute changes in routing table size 
around critical events on pages 9 through 11.   Fine time granularity 
is important to avoid missing all the interesting features.
