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.
