Just curious, replies off list welcome.
Seems visible in a handful of places: $ w3m -dump 'https://lg.ring.nlnog.net/prefix_detail/lg01/ipv4?q=104.244.42.0/24' | fgrep 8342 BGP.as_path: 198644 21283 8447 8359 8342 BGP.as_path: 8607 8359 8342 BGP.as_path: 16086 8359 8342 BGP.as_path: 31027 8359 8342 There is a RPKI ROA which only authorizes AS 13414 to originate that /24, chances are that RPKI ROV is helping limit the blast radius. https://console.rpki-client.org/rpki.arin.net/repository/arin-rpki-ta/5e4a23...
