My ISP's servers seemed to be synched from a continent away (based in Europe, using US servers), and had an asymmetrical path! In principle, though, it /might/ help to choose servers which are closer in connectivity than others - that's NTP connectivity of course. In practice, I tend to use two UK pool servers, and two University servers (Edinburgh and Manchester( which I have found to be reliable. These I have as a backup with minpoll=1024s. As I have two stratum-1 servers here as well, I would have to accept that four other servers could be said to be too many. http://www.satsignal.eu/mrtg/daily_ntp.html#Configuration Cheers, David _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
