I've now made pool 2 our default configuration address, in commit
503919fcf0 ("services: ntp: Default to an address that supports IPv6.").

On an IPv6-only network, the default configuration for ntp-service-type
doesn't work, because the default pool used (<0.guix.pool.ntp.org>)
doesn't have IPv6 addresses.

In fact, the <1.guix.pool.ntp.org> and <3.guix.pool.ntp.org> pools don't
have IPv6 addresses either. Only the <2.guix.pool.ntp.org> pool works
with IPv6.

Would it be possible to add IPv6 support to pools 0, 1 and 3?
