When a server loses all sources it does not necessarily become
unsuitable for downstream clients. Ordinarily, it inherits error
statistics from upstream servers and provides them to downstream
clients. Servers and clients use these statistics to calculate the

maximum error statistic which represents the maximum clock error
relative to the primary reference clock. See the error budget called out
in the specification. Once determined, the maximum error increases at a
rate (15 PPM) determined as the maximum disciplined clock frequency
error of the server clock. This increase continues indefinitely or until
the sources are again found.
