That's only true if the two devices have common failure modes,
though, is it not?
No, we can assume arbitrary fault which causes NTP to output bad time. With
two NTP servers it's more likely that any one of them will start doing
that than with one alone. And if any of the two start doing it, you don't
know which one.
Hey, waitaminnit! I saw you palm that card. :-)
If I'm locked to 2 coherent upstreams and one goes insane, I'm going to
know which one it is, because the other one will still match what I already
have running, no?
Or do I understand NTP less well than I think?
