> As an ISP how would you _guarantee_ the bandwidth for each endpoint?

When I still lived in Slovenia, I had 20/20 FTTH. Fiber went directly into a router in my bedroom. My bandwidth was always exactly 20/20. No matter what.

Now I have Comcast. Speedtest says I get 80/6. On Friday and Saturday evenings Netflix and Facebook and many other things often experience issues. Now I can't confirm any of this. If you run speedtest, it's fine. If you ping something, there's no packet loss. But it just doesn't feel very fast and reliable under normal use.

As someone living in Slovenia and still running on ADSL2+ I'm jelly. Regarding your 20/20, highly suspect, it's likely you were doing speedtest tests against your ISPs server which would make sense but you would never get that past their gateway.

I wasn't doing speedtests though, I was running torrents 24/7. High school was fun like that. Torrents were the only way to get music, movies, and TV shows back then.

This can't possibly be true. The ISP providing the service can only guarantee a particular speed to the boarder of their network.

Once you connect to a service not hosted by your ISP they can't guarantee anything.

Sure, they can't guarantee speed with a particular service, but they can guarantee width and reliability of my pipe. Believe me, back then I was downloading so much crap that my internet was stuffed full at all times. I'd notice any dip in service.

And when I was on ADSL, I did notice those dips. A lot of them. With FTTH, they went away.

There's a difference between "they guaranteed it to be that 100.000000% of the time" and "in practice, it actually was that the entire time". The latter can definitely be true.
