Hello List,
In search of stable, disparate stratum 1 NTP sources.
Looking for anyone=E2=80=99s advice/experiences (good/bad/ugly/weird) using=
NIST=E2=80=99s
NTP servers per: http://tf.nist.gov/tf-cgi/servers.cgi
We tried using =E2=80=9Ctime.nist.gov=E2=80=9D which returns varying round-=
robin addresses
(as the link says), but Cisco IOS resolved the FQDN and embedded the
numeric address in the =E2=80=9Cntp server=E2=80=9D config statement.
After letting the new server config go through a few days of update cycles,
the drift, offset and reachability stats are not anywhere as good as what
the stats for the Navy time server are - 192.5.41.41 / tock.usno.navy.mil.
I would greatly appreciate and feedback / advice, etc.
Thanks!!!
Ed
