> It's still the responsibility of the ISP to deliver connectivity to other hosts on the internet at their promised speed, regardless what is necessary to do so or how it operates internally
So they don’t have to deliver 1 gbps to every end point, they just need to “do a proper job” to make the bandwidth “usable.” But what does “proper job” mean? Historically, it has meant making reasonable efforts to reach interconnection agreements with other network operators. It has not meant that you’re required to upgrade your peering so that 50%+ of all your traffic can come from a single peer, at no cost to the other peer.

Because if all I am paying for is access (to Xfinity's servers), then they cannot in any way guaranteed even being able to get to a simple blog.
They're marketing copy needs to be looked at.
People like to pretend like internet access service is a promise to get your packets from point A to point B anywhere on the internet at a given speed. That is based on the fiction indulged by the software folks, who just think about getting bytes between a pair of sockets and don’t care how the internet actually works. But as explained in that Cisco article, interconnection and transit has always been distinct from access, and has been the subject of separate commercial negotiations between network operators. That reflects the technical reality that the internet is not a single network, but an agglomeration of private access and transit networks. The idealized software abstraction of the internet doesn’t define what it actually is. If you read the contract that defines what you're buying, it's not promising you that idealized abstraction.
