I did error somewhere, yes. If I didn't read that part, didn't send the right link, etc. Not sure. 


Yeah, single-homed on Cogent IPv6 is a problem. 


Maybe I just assumed that if you had transit from someone, that you got IPv4 and IPv6 service with them. Who doesn't do that?

Did you read the part about *IPv6* traffic ? 
Your link points to some IPv*4* relationship. Over IPv6, you get this : 

https://radar.qrator.net/as12322/ipv6-providers#startDate=2019-12-29&endDate=2020-03-29&tab=current 

Note the "Active Now" part, which is only active for Cogent. 

And then, rather than taking QRator (which does a good job and has interesting information on a number of things - who buys transit from who *NOT* being one of those things - or at least not the public information) as word of absolute truth, did you test that bgp.he.net thinks about this ? Since HE is one of the parties, it does make sense to check their tools to see their point of view. 

Long story short: 
- Free.fr in known in France (where I happen to live and work) for only having Cogent as a transit for the last few years. 
- they are also known to peer (like "only exchange own routes and customer routes") with some "very big" networks (usually called "tier-1") : level3 and zayo among them. 
- Cogent and HE over IPv6 ... I suppose everybody knows the story..... 
- Free.fr depeered he.net about one week ago... 

There have been some exchanges of tentative traceroutes in both directions on FRnOG (French NOG) and things are clear : free.fr and he.net cannot exchange IPv6 traffic.
