They can. Cogent has transit and is preventing traffic from traversing its

Cogent's court. This is not the first time or the second that they have
chosen to partition.
Cogent does purchase transit from Verio to Sprint, AOL, and other locations (but not to Level 3). Perhaps Dan would like to explain why that is relevant to the discussion at hand? Or why that puts the "ball" in Cogent's court?

And no, L3's "SFI" status does not mean it's Cogent's fault.

It is strange that people have to be reminded no network has the "right" to use any other network's resources without permission. Most people realize this in one direction. For instance, the "tier ones" love to point out Cogent has no "right" to peer with Level 3. Absolutely correct.

What some people seem to forget is that Level 3 has no right to force Cogent to buy transit to get to Level 3.

If Level 3 doesn't mind not being able to pass packets to Cogent, that's fine. If they do mind, they need to figure out a way to solve the problem - with Cogent. The inverse is true as well. As RAS said, it takes two to tango.

This problem will be solved "soon" (in human time - days, weeks at most). One of the networks may go out of business, but that "solves" the problem because there would no longer be locations on the Internet someone couldn't reach. I suspect it will be solved by less drastic means.


P.S. Does anyone else get that Baby Bell feeling whenever someone talks about being a "Tier One"?
