Sprint and Cogent

If you have followed the news, you may have come across this item last Friday. A more detailed technical description is here. The world of interconnection in the Internet is cloaked in non-disclosure agreements (NDAs), so when a story like this breaks, it is useful to look at it in more detail. Not surprisingly, both Sprint and Cogent were pointing fingers (see Sprint's version here, and Cogent's here).

As of this writing, the link has been temporarily restored, but you can expect that this will make waves again. It can be quite difficult for a carrier to maintain the traffic levels needed for peering, especially with a large ISP like Sprint.
