Re: Why do some companies get depeered and some don't?

Isn't it because the receiver is more likely to backhaul the traffic further, due to hot-potato routing - at least in the case of large networks with multiple points of interconnect?

Surely even assymetric peering agreements are mutually beneficial... ISPs are also content providers, either directly or through their customers... peering is going to have a flow-on effect in terms of reducing the cost of offering content to the people you peer with too, right?

Why all the focus on even or non-even-ness of up/down ratios in the first place?

What I mean is, how come networks like Teleglobe, Limelight, etc. don't get
depeered by others, but Cogent does? I'm sure Cogent isn't the only one with
bad ratios.
