Let me just add a bit of caution here:  The NTP software gets confused
if it has too many servers to select from.

I would _never_ advice configuring more than 5 ntp servers for any
machine, unless some of them deliberately are made unavailable and
only used for monitoring/sanity-check.

Never attribute to malice what can adequately be explained by incompetence.
