They usually are knowledgeable when I talk to them and they are able to do what I ask of them.  They usually don’t have to hand me off to somebody else.

Cogent has good DDOS RTBH also.  I trigger a /32 and it’s immediately black holed in the cloud.

Cogent does however have an issue with ipv6 peering with google.  I currently have my v6 ebgp session shut down with them because of this.  Moving forward and doing more V6 in the future, I will have to figure out how to deal with us.

I’ve also had Spectrum, ATT, Telia, all good as well.  I’ve have no experience with Zayo, so I can’t speak to that

We have 10G IPv4 circuits with both Zayo and Cogent getting full routes.  One major difference is the maintenance windows - when Cogent has maintenance, things get weird for hours at a time.

If you love yourself and your organization just peer with Zayo and not look back.

Zayo will provide you all of the internet

Cogent will provide you with something that is not all internet, it is missing HE and Google on ipv6.
