For small players, less than 4 sites, typically just use the NTP
pool servers, configuring 4 per box minimum.  If you want the same
protection I just outlined in the paragraph before, make 4 of your
servers talk to the outside world, and make everything else talk
to those.  Want to give back to the community?  Get a GPS/CDMA/Whatever

Choosing the first four servers is usually pretty straightforward:
*.CC.pool.ntp.org

But beyond that, I'm honestly rather curious what server selections
are a good idea. A first thought would be an adjacent country, but
maybe there is a benefit to picking things outside of the pool.ntp.org
selection entirely?

I see that Jared used *.fedora.pool.ntp.org -- I wonder if there was a
specific reason for that or if my questions are even worth thinking
about at all :-).


Happy to hear thoughts.
