Exactly. And this is why Cogent's statement to the public (and their
customers) is an outright lie. Level 3 isn't "denying Level 3's
customers access to Cogent's customers and denying Cogent's customers
access to Level 3 customers.". It's just that they deny Cogent
settlement-free direct peering anymore. Cogent can get the L3 and L3
customer routes elsewhere if they want. But Cogent doesn't. It's Cogents
decision to break connectivity, not L3's.

If I would be a Cogent customer, I would have a _very_ warm word with my
sales rep why they are trying to bs me with those kind of statements and
think that I actually am dumb enough to believe that.
