Cogent's business model is spectacular. Its all about bulk. They have one of the best data networks on the globe. We should see other big tier 1 providers doing the same thing as cogent. It doesn't cost these companies nearly as much as they are charging to run the network. Cogent is just bringing competition to the ball game. I loved how cogent sent letters to level 3 customers who were affected by the disconnect, offering the customers a great discount on their service. I hope they do the same to this swedish company.

Cogent's business model is only spectacular if your not a peer having to intake hundreds of TB's of their traffic, while outputting very little of your traffic to their network.

It's the equivalent of you splitting the water bill with your roomate 50/50 and then finding out your roommate takes 6 showers a day, owns 9 aquariums, and likes to listen to the sound of running water just because it makes him giggle.

Other data providers aren't "jealous" of Cogent's model, they just aren't blatant assholes. If they truly wanted to get into a pricing war with Cogent they easily could and would not need to resort to harming customers on both sides like they do everytime a peering agreement is unexpectedly cut.
