I'd guess the probability of complete failure is much lower in that case. Further, Cisco at least, recommends using at least 3 NTP sources to help maintain sanity on the equipment using the NTP. The bug you reference by the way, is on a page dated from 1999. I'm not sure of the relevancy now. Does anyone on the NANOG list actually deploy standalone equipment ???
