The figures come from the routing tables our peers give us. This number is seen from 6 separate vantage points. A peer that shares an internet exchange with this network and carries only a small share of its paths is not counted as an upstream: a transit provider carries the whole table, an IX peer only its own announcements. Internet exchange data comes from PeeringDB. Figures are from a dump taken 3 hours ago.
