Bill,

I did not change "whenever I demand it" to "all the time". You're hand-waving 
now. I clearly said that users can't all demand their maximum bandwidth at the 
same time. That's nothing like "all the time."

Every house can't use its 200 amps at the same time, which happens when 
everyone turns on their AC on a hot day. The electrical grid is not built to 
the worst case scenario, and it does in fact break down when those events 
happen.

Your shower example is perfect. Yes, you can get 120A tankless water heating 
for a brief interval. But not "whenever you demand it." If you demand it while 
the everyone is experiencing an HVAC-induced brownout on a hot day, your won't 
get it. Period.

You never responded to my "BillsNet" real-world example. Is that a straw-man 
argument too?

In what way is my argument a straw man? I specifically address
the assertion you make, that an ISP must deliver X Mbps

essential practice of oversubscription.

You changed "whenever I demand it" to "all the time" and then
proceeded to argue that if everybody used their whole bandwidth all
the time, oversubscription wouldn't work and therefore Internet
connections would cost thousands of dollars.

Well sure, if every house used 200 amps all the time the electric gird
would collapse. Yet somehow when my 120 amp tankless electric water
heater kicks on for my morning shower I don't black out the city. How
could that possibly be?

It's a straw man, Mel. Own up to it and move on.

Bill Herrin
