The host security-cdn.debian.org, used by some packages on
security.debian.org¹, despite having an IPv6 address in the DNS, can not
actually be reached from an IPv6-only host, due to issues with DNS
hosting by Fastly, the CDN provider.  I raised this problem with Fastly,
first on IRC and then in their issue tracker, but their response is, as
you can see, "IPv4 is required and we have no plans to change this.".

Does Fastly claim IPv6-reachability to Debian in their CDN offering?

See attached correspondence.
