Thankyou sir!

As noted by Matthew, anyone needing that level of resolution should be doing it themselves, but I'd love to see how a real world NTP implementation on the network here in NZ stacks up against local GPS unit so every little bit of info helps.

I think the issue is that with 3 clocks, if 1 fails, you are left in a situation where NTP can't tell which remaining clock to trust.

I'd also be interested to know precisely where the servers are physically connected. While NTP is really very good at dealing with latency, it can't deal with asymmetry in the forward and return paths (it assumes one way delay = 0.5xRTT). I'd be curious to see how many people have symmetric routes to the servers.

We should be able to add what you need to the web site without giving away the exact physical location.
