I've just had to set up in-house NTP properly at my new job, and my
approach was to take 3 OpenAccess servers from the strat 2 list at
ntp.org, and 3 us.pool server, and set those up as the peers for both
of my edge servers, which are on different backbones. I then peered
them both to each other, and I'm going to tell my DHCP server to hand
out both internal addresses to my 25 servers and 280 workstations.
That's, I think, a big enough cloud to justify that many servers
upstream...
Amusingly enough, time.nist.gov was one of the pool servers. :-)
