And that in no way way means you should dump peering. What if peering > is cheaper than transit? Cost of transport, opex and capital to build out to a peering point, ports for interconnect, vs the expected money saved by peering away sufficient traffic is the analysis that will inform your strategy. This is why I said if you are already at a place where you are buying transit, it probably worth it to peer with the folks locally. The point is if you are building out specifically to peer, the effort is not worth it if you are not operating at scale, and if you are operating at scale, you are not going to ask nanog about peering. /vijay > > The part where we do agree is that most people cannot figure out their COGS. > And you might even convince me that "you don't know what peering really > costs you" is a valid reason to shy away from it.
