netblocks at their boundaries.

I mean, simply de-peering shouldn't totally terminate all connectivity
between L3 customers and Cogent customers, should it? One of the great
appeals of this intarwebnet thingy is that it routes around outages,
right? L3 *can't* be Cogent's *only* upstream provider, right? :)
