You can connect more than one stratum-0 reference to each server,
additionally peer them, additionally connect other (public) servers, and
define the system clock as fallback.
E.g. I have two time servers, each with 3 radio clocks, 5 public
servers, and the system clock as fallback. Usally one of the radio
clocks wins, but short before or during thunderstorms one of the public
In a configuration of 10 servers, each with GPS directly connected, I
would peer them.
