Inferred from path position, not from any declaration by either party. A network appearing here is carrying these routes; whether that is a paid transit arrangement, a backup, or something else is not something routing data can tell you.
Derived from routing tables collected at 2026-10-14 10:00 UTC by route-views2,rrc00, as seen from 75 BGP vantage points across 73.25M route entries. These are observations from those vantage points, not a complete or authoritative view of the internet.
