[time-nuts] Does GPS time reception work everywhere all of thetime?

Hi
On the other hand, NTP gets bothered if it has only 2 independent partners.
It's quite happy with one, but two seems to bother it. Three or four seems
to be a "sweet spot".

Still beating on the email problem... seems to be a router somewhere in Ohio
or Illinois that's the issue. May get fixed some day, until then no incoming
email.

Let me just add a bit of caution here: The NTP software gets confused
if it has too many servers to select from.
I would _never_ advice configuring more than 5 ntp servers for any
machine, unless some of them deliberately are made unavailable and
only used for monitoring/sanity-check.

Never attribute to malice what can adequately be explained by incompetence.
