Hi,

And for the record, not only have I never worked for an ISP, I was
saying all the way back in the late '90s that the oversubscription
business model (which almost always includes punishing users who
actually use their bandwidth) is inherently unfair to the customers, and
when the Internet becomes more pervasive in daily life will come back to
bite them in the ass. I was laughed at for being hopelessly naive, not
understanding how the bandwidth business works, etc.

I have worked for ISPs. And I remember the late 90s. Bandwidth was $35/mbit
on average, at least for the outfit where I was. Consumers paid roughly $40
for their DSL connections, which at the time went up to 2Mbit depending
on the age of the copper and distance to the DSLAM. Consumer connections
were oversubscribed, on average, 1:35 to 1:50. B2B connections got a better
deal, 1:10 to 1:15.

It was simply not feasible to offer 1:1 bandwidth and still make a profit,
unless you're charging fees the average consumer cannot afford. 

Especially considering that the average user doesn't even need or use that
much bandwidth. It's a recurring discussion. People demand more bandwidth
without considering whether or not they need it. End-users, business subs,
and host-owners at large enterprises where I worked. The last ones are the
funniest: entire racks using no more than 100mbit/s and hostowners are 
demanding an upgrade from 10G to 25G bEcaUse LaTenCy.

The last consumer ISP I worked at had a very small subset of users that 
really needed bandwidth: the "download dudes" who were 24/7 leeching news
servers, and the inevitable gamers that complained about the latency due
to the links being full as a result of said leechers. In that case, a
carefully implemented shaping of tcp/119 did the trick.

Thanks,

Sabri
