Hi Hank,

Again:
* 217.208 unique prefixes detected by the RIS server in Moscow (ASpath: 2895 3267 8997 & ASpath 2895 5431 3267 8997)
* 250495 seen by routeviews (ASpath: 3277 3267 8997).

Looks like those are the only ones, but this is just a quick egrep, awk, and sort on the rawdata so I might have missed something (It's getting late here, so no guarantees ;))

Cheers,
 Andree
