Naturally, given my role as Co-Founder and Chief Technical Liaison for Equinix, I wanted to understand when and why they used IXPs. I asked for the types of questions they asked of IXPs and I tried to understand their decision process. After hundreds of conversations and taking lots of notes, I had documented the collective peering community view of IXPs. To the ISP and IXP community, the information in this chapter is valuable.
