pool.ntp.org is great but if using it I would recommend to use MANY
of its servers, preferably in combination with any servers your
upstream may supply.  Servers in pool.ntp.org are run by volunteers
and I have sene them occasionally be insane for a short while before
the pool's monitoring detects that and throws them out.

Also ntpd sticks with the servers it was given when it started so
servers being added or dropped from the pool won't change matters.
It does however have its own scoring mechanisms to drop false
tickers hence I say use more servers.

Cheers,
Andy
