Re: bgpmap.net - free multi-vantage BGP looking glass

Hi everyone,

A short update on bgpmap.net, which I introduced here a few weeks
ago: every lookup now queries RIPE RIS and the RouteViews API in
parallel and merges the paths into a single graph. Peers that feed
both projects are counted once. Each result shows how many peers
came from each source, and the raw responses from both can be
downloaded.

Two examples:
https://bgpmap.net/s/5zxyhbbtdj (8.8.8.8)
https://bgpmap.net/s/zx293h38md and https://bgpmap.net/s/nef7mu8jbr (a /27 seen only by one RouteViews
peer in Sydney, invisible to RIS)

The merge rules are documented here:
https://bgpmap.net/methodology#sources

Feedback is very welcome, especially on the merge logic.

Thank you,
Matin
