Not knowing what country your from but at a U.S. taxpayer I have no reservations about using time.nist.gov myself, some people think it's rude to directly query stratum 1 servers. I typically have 2-3 NTP servers per location behind a load balancer and my internal servers sync against the load balanced VIP, and the NTP servers themselves sync against time.nist.gov nate I'm not trying to hijack this thread but I have a question about how typical this is for *core* infrastructure services. Do you load balance other services as well? I'm thinking of dns, ldap, proxy, internal web servers like a cms, radius, and probably more but those are some of the services I try to make fault tolerant. Thanks.
