Fun fact: Per [0], if you provide enough servers, the NTP client can detect a "falseticker" that is not providing accurate time. The number of NTP servers required is `2n+1` where `n≥1`. Of course, that requires each NTP server use its own time source. So, note for me: If I want NTP redundanc…
This was implied by them taking the time and effort to establish multiple sites.
