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?
