I wonder, if a host has a global IPv6 address that is not derived from any kind of transition technology or tunnel, and setting up a TCP connection is either slow or fails, then what percentage is due to an issue close to the host and what percentage close to the target.
I.e., if IPv6 is broken is there any reason to believe it is often enough due to ISP provided services that is would be worth reporting it in a roudabout way.
I'd say that it is much more likely to be broken close to clients, at least for Alexa web sites..
We cannot generalise this without empirical data.
There is also v6 brokenness (or slowness) in ALEXA websites also that not hosted by large CDNs.
Every category of webbservers have problem with IPv6 Look at https://www.myndighetermedipv6.se/ -> "Authorities with AAAA in its www..”, more than 10% does not work over IPv6 today. Another common IPv6 problem is the the firewall/load balancer where http work and https does not. With IPv4 it does https://ipv6alizer.se/?address=https://www.gavle.se https://ipv6alizer.se/?address=http://www.gavle.se ( https://ipv6alizer.se ’s main mission is the PTB-problem but it also tell us when it don’t work at all. ) Why does the owners don’t see this problems? The users don’t have IPv6 on the inside and they are the best monitors. /Tobbe
