Note:
These are observed adjacencies derived from BGP path data, not confirmed commercial relationships. A network appearing before another in an AS path does not establish that it is a paying transit customer, a settlement free peer, or anything else contractual. Adjacencies marked uncertain were seen only as direct peers of a route collector, so the collector's own peering may have created them.
