anecdote: most of the internet troubles at rust belt rust would have gone unnoticed if ipv6 would have worked for the mentioned sites that don’t have ipv6 support.
Thanks for the post! Always good to check up on these sorts of things
I’ve enabled IPv6 for the CloudFront distributions of static.rust-lang.org and www.rust-lang.org (note that rust-lang.org is a DNS-provider-redirect and may not be ipv6 yet).
Unfortunately Heroku, where crates.io is hosted, does not have IPv6 support yet. Additionally, rustup.rs along with domains like doc.rust-lang.org are hosted directly on EC2 which unfortunately doesn’t have direct IPv6 access either.
