All in all, this raises an interesting question. Is British Telecom running

What happened is pretty clear, and not just for BT or SK.  Those providers,
as a business decision, built their business models around a certain level
of oversubscription that would strike a balance between customers not being
unhappy and squeezing as much headroom out of the network before upgrades
are required (beefier routers/switches, fatter pipes, more peering/transit,
etc).  That business model got upended when that acceptable level of
oversubscription changed.  Video streaming was the puddle of
gasoline/petrol on the floor, and the change in user traffic patterns was
the lit match.

By asking content providers to hand over money to those carriers in
exchange for (better) access to their customers, many of the ISPs could in
fact be triple-dipping because they already get revenue from their
customers and some also get various government subsidies to provide certain
types of service or services in certain areas.

Definitely doesn't pass the sniff test.

Thank you
