[pkg-ntp-maintainers] Bug#442946: *.debian.pool.ntp.org do not exist on 4 of 5 pool.ntp.org name servers

[Adam M. Costello]

Package: ntp
Version: 1:4.2.4p3+dfsg-1
Severity: grave
Justification: renders package unusable

Of the five name servers for pool.ntp.org, four of them claim there is no
such host as 1.debian.pool.ntp.org, etc.  To investigate this:

dig -t ns pool.ntp.org
# Shows the name servers to be [a-e].ntpns.org.
dig @a.ntpns.org 1.debian.pool.ntp.org
dig @b.ntpns.org 1.debian.pool.ntp.org
dig @c.ntpns.org 1.debian.pool.ntp.org
dig @d.ntpns.org 1.debian.pool.ntp.org
dig @e.ntpns.org 1.debian.pool.ntp.org

I find that only b.ntpns.org knows of 1.debian.pool.ntp.org (and the
other digits).  I've observed that 1.debian.pool.ntp.org resolves
on some systems and not on others, which is what you'd expect from
inconsistent authoritative servers.

This problem can be worked around by reverting the config to use
pool.ntp.org.
