Hi,

Hmm. Currently, I have 3 monitoring servers in action - one in the US, one 
in .nz and my own server, here in .ch.

Looking at the log of those, over the last two days or so, shows that all 
three thought that your server was unreachable most of the time:

The log starts 2003-11-08; the fields are time, score, status (first char of 
ntpq -p output), delay, offset, jitter (as ntpq reports, too).

[log data below]

I can't give you a solution - I guess that outgoing packets get lost (which is 
why you'd not see the problem in monlist output).
