`dev-desktop-us-1` does not respond on IPv6

[cuviper]

It looks like dev-desktop-us-1.infra.rust-lang.org has dual-stack networking:

$ host dev-desktop-us-1.infra.rust-lang.org
dev-desktop-us-1.infra.rust-lang.org has address 44.204.37.156
dev-desktop-us-1.infra.rust-lang.org has IPv6 address 2600:1f18:619f:e701:fee2:1ae2:4384:ed4c

However, I don't get any response on IPv6. This is annoying because my ssh seems to try IPv6 first by default, whereas ssh -4 connects to this host fine. For now, I've forced it to AddressFamily inet in my ssh_config.

I don't need IPv6 access, but it shouldn't be in DNS if it doesn't work. In comparison, us-2 only advertises IPv4.

It looks like eu-1 and eu-2 are in the same situation.

Thanks for reporting this! I'll have a look tomorrow or next week.
