I don't see why this is necessarily the case. Since the DNS server
necessarily does remote connections to obtain the IP addresses, it
could be a general network problem beyond the DNS server.
Note that once the DNS server has obtained the IP address, there
are no longer any issue with it ("dig" always succeeds for this
host). Only getaddrinfo still fails to give the IPv4 address with
AF_UNSPEC.
