Upstream graph

The networks AS39572 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS39572 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
