Re: hmmm

If we are talking about the same thing.. it's because these ISPs didn't pay their Level3 bills.

There was no bill. It was a peering agreement. The ISP's and L3 agreed to carry traffic for each other, for free. Kind of a "you scratch my back and I'll scratch yours" sort of thing.

L3 carried more traffic for the ISP's than the ISP's for L3. L3 decided this arrangement was no longer fair and wanted financial compensation. Unfortunately, there was a contract binding them to the free arrangement.

L3 wanted money, but the ISP's cited the contract and L3's free obligation causing a stalemate. That's were it started.

L3 said "Give me money!"

The ISP's said "Um, no, the contract says you will provide this service at no charge because we carry your traffic too!"

L3 said "Fine, I will just unplug you, contract or no contract, and you won't get plugged back in until you come up with some cash!"

And that's that. Finally, L3 agreed to resume peering services with the ISP's until an agreement for compensation could be reached.

I think you misunderstand, it was a dispute between Level 3 and the other backbone provider (I'll call them cogent because I am not sure if that's their name.)

RR and other ISPs had peering agreements with Level 3 I believe.

Cogent had a peering agreement with Level 3.

Traffic was disproportional, Level 3 demanded cogent to pay.

Cogent kind-of ignored that...

Level 3 in turn told their routers to tell ISP's customers that there were no routes to cogent's customers (instead of the correct route which would be to specify an alternate route to the cogent customers).

RR and other ISP's customers could not access anything on the cogent backbone because Level 3 blocked them. This blocked many many legit websites, and was no fault of said websites webmasters nor the ISPs.

If any of this is wrong feel free to correct me, that's just what I understand of the issue.
