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 :-).
Ah; the question that has plagued mankind since the beginning of.. time. :-) There are a couple of documents on this topic at ntp.org, and there's the traditional list -- of questionable accuracy at this point -- of open-acess Strat 1 and 2 servers. For myself, I usually pick the first three in us.pool.ntp.org, tick and tock, time.nist.gov, and a couple of regionally appropriate large universities. I have always aimed for 6 to 8 outside servers, and a pair inside, preferably in different locations, both talking to one another. If your site is in Internet Business, you should probably peer with your business partners. If you deal with Google Docs or AWS, you should probably peer with them, if they have servers for that.
