So I just found out that the IX we're looking to hook up with (Equinix) doesn't allow downstream ASes. How does that functionally work?
Stepping outside my ISP for a moment, I know a building owner with several buildings that provides Internet to his tenants. He's getting an AS so he can have upstream diversity. Unless carrier A or ISP B have direct private peering with whomever (Amazon, NetFlix, Google, FaceBook, etc., etc.), that building owner doesn't have a route to those services? They can't utilize carrier A or ISP B's public peering connection? How can that possibly bee with with every ISP being required to have their own physical presence on the exchange? That's just not practical.
I understand not having parallel ASNs (advertising both ASN A and ASN B separately) from a sales perspective, but I don't understand ASN A advertising directly on the IX, but not allowing ASN A's downstream customers of ASNs B, C, D and E.
Am I wrong or is this just an Equinix thing?
