Where the world peers
You hear “Frankfurt is the largest peering hub in Europe” or “Ashburn is the world’s biggest” — but the actual ranking depends on what you measure. This one uses aggregate PeeringDB network presence across every tracked facility in the metro. The top 20 metros together host 25,520 network presences.
#1 is Jakarta with 2,804 network presences spread across 96 facilities.

“Network presence” sums each network counted at each facility — so a network peering at five Frankfurt buildings adds five to Frankfurt’s total. The headline alternative is unique-network count per metro, which favors broader-distribution metros over deep-concentration ones. This ranking captures interconnect weight, not unique reach.
