> Can you really talk to their stuff on ipv6 from GCP? Nope. Until now it was impossible because you couldn't get v6 on GCP, so it was only useful for communicating with GCP APIs externally. Strangely, even now you can't talk to their stuff over IPv6 from GCE, because of this: "Connecting to Google APIs and services using external IPv6 addresses is currently not supported and will result in a destination unreachable ICMP response." IIRC, S3 also got v6 support some time before EC2 instances could get v6 addresses, but I don't recall this kind of weird internally connectivity breakage on AWS when EC2 rolled out v6. Google must be doing something weird with their internal routing.

I think you are right - weird or so cool it doesn't play well with ipv6? Yeah, AWS ALSO had the issue of ipv6 on various services long before EC2 which was frustrating (I think you could terminate IPv6 at load balancer before they had IPv6 on instances?). They tend to support services much longer so I think did the dual stack endpoints as separate endpoints in case someone had built something where if an intermediate or base DNS got updated and started providing IPv6 customer apps wouldn't break. Google used to be much more get out of our way in terms of closing down / depreciation systems - so your stuff was always breaking - but on the upside they could do cleaner approaches (one set of endpoints etc). I've heard they've gotten some feedback that doesn't work so well on enterprise side so are dialing it back.
