I guess what I'm getting at is that it sounds like, if you cannot source the content locally to the peering link, there's not likely to be an internal connection to the same site from somewhere else within the Akamai network to deliver that content and, instead, the target network should expect it to come in over the "public Internet" via some other connection. Is that accurate?
I believe this is true of multiple content networks. For example, we peer with Amazon in a couple of locations, but a significant amount of traffic frmo their AS comes across transit rather than peering. In old terms, this is "hot potato" routing - where the source gets the traffic out of their network as soon as possible, rather than spend internal resources to carry it as close to the destination as they can. -- Chris Adams <cma@cmadams.net>
