For resiliency (so that one can be offline or unreachable for an extended period, and lets face it, this is the Internet) you need 4.
I agree, four is best in case one goes and the remaining two disagree. Paranoid but not unknown. It's a weakness of ntp.net.nz that we only have three and something we would like to address at some point this year. Jay
Others disagree and consider a bad ticker to be a fault that should be resolved just like poor connectivity, and only engineer for one of these situations at a time. You can choose :-)
