Google and HE don't have IPv6 connectivity with Cogent because Cogent's CEO has been in some decades long pissing match with them about free settlement free peering. That's the unfortunate reality of the situation; nothing you can do other than have another route to HE/Google IPv6 targets. We have some Cogent circuits that are effectively useless for IPv6 as our customer base has heavy traffic to/from Google cloud services, so they can't be used for a backup / DR scenario; their only real value is an optimal route to other Cogent customers. I'm slowly replacing our Cogent circuits when feasible because the reality is our customers reaching Google over IPv6 via all our upstreams is more valuable than Cogent's cost savings.On 12/20/18, 12:37 PM, "NANOG on behalf of Brian J.

But I think it getting that far time was an anomaly and frankly it usually dies even before exiting my ISP's (Cogeco) network like this:Host Loss% Snt Last Avg Best Wrst StDev 1. 2001:1970:5261:d600::1 0.0% 33 0.6 0.7 0.6 1.0 0.1 2. 2001:1970:4000:82::1 0.0% 33 8.2 10.8 8.1 40.5 5.6 3. 2001:1970:0:1a7::1 15.2% 33 23.4 20.1 16.5 23.4 1.5 4. 2001:1970:0:61::1 33.3% 33 16.8 17.6 14.5 25.9 2.5 5. 2001:1978:1300::1 0.0% 33 16.0 17.5 14.2 29.6 3.1 6. 2001:1978:203::45 0.0% 33 30.7 30.7 28.4 35.1 1.77. ??? When I asked the kind folks at he.net for some advice about the problem (i.e. in the first traceroute above) their diagnosis was that Facebook's IPv6 router(s) likely didn't have a route back to my Cogeco IPv6 address. Trying to talk to my ISP (again, Cogeco) has been impossible. One simply cannot reach the people who know more than how to reset your router and configure your e-mail. I wonder how I could go any further with this to confirm the diagnosis that Facebook doesn't have a route to the Cogeco network's IPv6 address space given that I only have access to my end of the path.
