Performance limitations in the current Internet are thought to lie at
the edges of the network -- i.e last mile connectivity to users, or ac­
cess links of stub ASes. As these links are upgraded, however,
it is important to consider where new bottlenecks and hot­spots
are likely to arise. Through an extensive measurement study, we
discover, classify and characterize non­access bottleneck links in
terms of their location, latency and available capacity. We find that
nearly half of the paths explored have a non­access bottleneck with
