What good will having more servers do then? If the probablility of 4 bad ones is that high, the probability of 5 out of 9 is also high, and 6 out of 11. Ie, in that case you are basically screwed. Of course everyone could just use the national time standards servers-- they are not liable to be wrong (maybe just overloaded). > > _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
