This pretty much is what I'm looking for except that the
data are weird.  The archives here list only about 65K
routes:
http://www-01.pch.net/resources/data/routing-tables/archive/2011/netnod.woodynet.pch.net/
There may be some kind of truncation problem.

So then I tried this one:
http://www-01.pch.net/resources/data/routing-tables/archive/2011/route-collector.ams.pch.net/
and it lists only ~173K prefixes.

When I look here
http://bgp.potaroo.net/
it seems like I should find on the order
of 350K prefixes.

What am I doing wrong?
