Currently, the ipv6 reachability of websites operated by the rust team is pretty bad. ## Sites with ipv6 support - `internals.rust-lang.org` - `users.rust-lang.org` ## Sites without IPv6 support - `crates.io`; probably the most important rust related site - `static.rust-lang.org` - `rust-lang.org` - `rustup.rs` These are just the sites that I can recall, but there are probably many more. I’m not listing [docs.rs](http://docs.rs) here because its maintained by the community. But, that site does have ipv6. I know that a large part if not all of those sites are hosted on amazon’s cloud. It seems they support ipv6 since August this year: [https://aws.amazon.com/blogs/aws/now-available-ipv6-support-for-amazon-s3/](https://aws.amazon.com/blogs/aws/now-available-ipv6-support-for-amazon-s3/) ---

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. ---

Thanks for enabling ipv6 at those two places! That’s a good start. ---

@alexcrichton apparently, IPV6 support has arrived for EC2: [https://aws.amazon.com/blogs/aws/new-ipv6-support-for-ec2-instances-in-virtual-private-clouds/](https://aws.amazon.com/blogs/aws/new-ipv6-support-for-ec2-instances-in-virtual-private-clouds/) ---

Unfortunately all our instances are in “EC2 Classic” and not in a VPC, so I don’t think that feature is available to us yet ☹ ---
