Hi,
As I discussed at the IEPG in Adelaide Australia, I have been posting weekly stats about the state of the Asia Pacific routing table to the AP Operators mailing list (apops@lists.apnic.net).
Basically I am examining the view of the Internet routing table as obtained from NSPIXP2 in Tokyo, mostly for the benefit of the region's ISPs. At the same time I have been producing statistics for the region covered by the RIPE NCC (and for the region covered by ARIN).
Would it be interesting if I posted the European summary to this list? It is no more intrusive than the CIDR Report which Tony Bates posts on a weekly basis, and gives what I believe is a view which is more focused on the region covered by the RIPE NCC. I've included a sample output at the end of this e-mail, fyi.
More information is displayed in graphical form on the APNIC web page, specifically:
http://www.apnic.net/stats/bgp
best wishes!
