begin Jeff Miller quotation:
> How local? Here are some from a list by Thinking Man Software:
>
> clock.llnl.gov Lawrence Livermore National Laboratory
This was a stratum 1 (primary) server, but is listed (in the NBS
listings) as "deleted".
> wave.mbari.org Monterey Bay Aquarium
This was also stratum 1, and is now listed as "discontinued service".
> norad.arc.nasa.gov Ames Research Center, Sunnyvale
Not listed.
> clock.isc.org Internet Software Consortium, Palo Alto
This is a stratum 1 server.
It's a really, really bad idea to synchronise off a stratum 1 server, from
multiple points of view. For one thing, when the site's sysadmin (or
his script) figures out where the traffic come and verifies that you're
yet another person trying to grab a stratum-1 connection without
approval, he'll probably shut out your entire IP netblock. Which will
then result in your net neighbours getting annoyed with you.
Use _secondary_ NTP servers (only) for ordinary time-sync purposes: You
can afford a few milliseconds worth of error. (If not, do your
time-sync by shortwave.)
