Maybe I just wasn't clever enough to figure this out, but I had (wrongly) assumed that "the list" was the preferred means of finding good servers, and that using the pool to find upstream servers was not recommended but permissible. So I (again wrongly) assumed most pool servers would be stratum3. Oops! > PS.

That indeed gives some decent results, but the problem remains that the first suggestion to potential pool joiners is to use a list which has a lot (at least 270) of defunct servers. I've been a server admin for over a decade, and my bash skills are still sorely lacking compared to what you've just done. One of my ideas was to create a tool that would allow a user to pick a locale/iso code and then give them a randomly chosen list of 5 known working servers from their region (taken of course from the list). Now that I've seen your command, what if the pool site had a way of letting a potential pool server operator pick their region, pick a stratum, and then give them a list of 10-15 servers to pick from. I'd certainly have been ok with something like that (even if I'm a bit OCD sometimes). Or perhaps some guidance on easy ways to find good upstream servers from within the pool. I was honestly a bit shocked at the ratio of stratum 1 & 2 servers in that query. Only 1 (out of 16) was stratum 3. At any rate, I've communicated directly with Brad, Harlan and the team at ntp.org because as long as the stratum 2 list is linked from www.pool.ntp.org (and Google for that matter), people will use it, and I want to make it better.
