This is disingenuous. Yes, an ISP can’t do anything if you pay for 1Gbps but can’t download that fast from a server in Turkey. But the only reason a customer can’t get sufficient bandwidth from Netflix, whose servers are often 5 hops away in the same city, is because the ISP is not doing their job. Being an ISP implies also doing a proper job of setting up agreements such that the bandwidth you pay for is usable.

You’re backing off from your original assertion:

> 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.

I’m not backing off my argument; I’m arguing from a stance of reasonableness rather than perfection. And while we can argue on exactly what defines “reasonableness”, I think it’s unambiguously clear that a large number of people do in fact need 50% of their traffic to come from a single peer and I think it shouldn’t be unreasonable to expect an ISPs to address that rather than throttling customers. I know plenty of people whose internet usage consists of email, Facebook and hours upon hours of streaming Netflix.
