We were synchronized against multiple sources. Unfortunately the Navy NTP source contaminated multiple downstream sources. Unless you can trace all your sources, if these sources all have a root source you will break.
"... against multiple [Stratum 1] sources..." Baby, if you've ever wondered... whether it matters whether your sources are strat 1 or not, now you know -- since there's no real way to get provenance on down-strat time sources that I'm aware of. Does the NTP code, people who know, give any extra credence to strat-1 sources in it's byzantine code? Cheers, -- jra -- Jay R.
