Downstream customers

Peering & transit neighbours (CAIDA)

Inferred AS-level relationships: 2 upstream providers, 1 peers and 1 downstream customers. The graph shows the largest few of each; the lists link through.

Relationships are inferred from BGP by CAIDA and refreshed monthly. Transit links are well captured; some private and IXP peering is under-observed, so peer counts are a lower bound.
