Well, as you may have seen in the newsletter, I've replaced the monitoring 
system - that was 3 days ago.

Right now, I can, indeed, get no time with ntpdate:
vbi at altfrangg:~$ ntpdate -q 216.27.185.42
server 216.27.185.42, stratum 0, offset 0.000000, delay 0.00000
10 Sep 11:46:43 ntpdate[3539]: no server suitable for synchronization found


The new monitoring system does, essentially, exactly this (except that it 
only sends one packet - since servers are queried every hour, occasional 
instablilities should even out over time.)

In the plot on 
<http://www.pool.ntp.org/scores/show_server_stats_do_graph.php?server_ip=216.27.185.42> 
you can see that the instabilities started with the old system (right now, 
8 days ago), then the monitoring system was down 3 days (streight line, 
going down because I made a mysterious mistake - score should have stayed 
the same, really), and then the new monitoring system cut in, showing the 
same kind of instability.

I can't say what the problem is, but the fact that both with the old and the 
new system your server seems to be instable makes me think that the problem 
is not with the monitoring system.

Perhaps some people (in various locations) on the list want to enter that 
server in their ntp configuration and report after a few days?
