I suspect it is the number of times that ntpd tries to contact the
server and fails rather than the time that is important. You could try
putting the server offline and then online again (I use chrony so do not
remember if ntpd has that option).

No, it doesn't.


You could use a one line cron script to restart every day, week,
whenever...

Or for $14/machine I could use a USB GPS, my machine with PPS GPS, and a
public server that does not request use of DNS.

You could try specifying the server by IP rather than by name, so DNS is
not needed. Of course this rule out using pool, unless you put them in
by IP. DNS is just used to translate names to IP, so if you use IP, then
DNS is not needed.


Or for $14/machine I could use a USB GPS, my machine with PPS GPS, and A
public server that does NOT request use of DNS which yields 3 sources of
time without using a pool or DNS lookups.

Or for $28/machine I could use 2 USB GPS receivers and my machine with
PPS GPS, which also provides 3 sources of time without any network
access at all.



Your choice, but when I registered the ntp server here with the pool, I
just used the fixed ip address. That's what they ask for and it does
bypass dns altogether. The less translation the better, unless
you really need it...
