Inside the very "center" of the internet is a set of networks run by companies who have a special arrangement with each other that the rest of us do not have, These are sometimes called the "tier ones" or "transit free networks"

However, are all of these "transit free networks" actually free of transit, and what does that actually mean?

In this talk will go over some of the bgp.tools data that I have been analysing that will show have some of the T1 peering issues, where gaps exist, and how certain networks are getting closer to becoming a them, and what are the problems they will probably face, and finally does a network even want to be in this situation
