Whats going on at Cogent

Our network is connected as follows:

1) We are fully IPv6 deployed
2) We have direct peerings with Google, Apple, Microsoft, Akamai,
Cloudflare, etc
3) We have cache servers from Netflix and Akamai
4) We are peered with the route servers on NL-IX and STHIX CPH.
5) Transit from HE, Cogent, GlobalConnect.

I am not doing anything to force traffic to the Cogent link (why would I?).
But I am not doing anything to force it off either.

The nice people at Cogent will regularly call me and ask if I want to buy
more transit. However I can not make their network deliver more traffic. I
only fully control the outbound and that is a small fraction of our inbound.

I understand that measured by "AS rank" Cogent might have more, but that
does not translate to traffic in our case.  This got to be a problem for
