Cut and paste error?  They should all look more like:

Yes, that is exactly what it looks like before Mozilla Compose
mutilated them
in producing "plain text."
Those domains all resolve, here.  But I don't think you're doing
yourself any favours by referring to a bunch of NTP servers at the same
location.  You want a collection of different servers, else you might
believe a set of servers to be true, that believe themselves to all be
true, when they're not (they might all be referencing themselves).
Originally I had three different sources within a few hundred miles in
hope of minimizing delays, some went away over time and the two left
always
worked well enough for my purposes.  Your suggestion is obviously
valid. But I still can't see what's happening, since ntpq doesn't
work even when I
reduce the list to just the Redhat server.
I picked a collection that come from different locations:

server 0.pool.ntp.org iburst
server 1.pool.ntp.org iburst
server 2.pool.ntp.org iburst

Plus a couple of more local ones, to me (au.pool.ntp.org and my ISP's)
I can do something similar but first need to fix my problem.
Any hints/errors in /var/log/ntp?
I haven't found any such log, locate *log*ntp* produces nothing I
recognize as useful?

I did find:  /usr/bin/ntpstat
synchronised to NTP server (198.82.1.203) at stratum 3
  time correct to within 79 ms
  polling server every 512 s

Which seems to indicate ntp is working at least but I don't have the
convenient data display I am accustomed to.

Why not try using ntpq in interactive mode.  Use -i to get to that
state.  Then raise the debug level with "debug more" and try "peers".

Ed
This is what I got ;

ntpq -i
Name or service not known
ntpq> debug more
debug level set to 1
ntpq> peers
***No host open, use `host' command
ntpq> host 198.82.1.203
current host set to 198.82.1.203
ntpq> peers
198.82.1.203: timed out, nothing received
***Request timed out
ntpq> debug more
debug level set to 2
ntpq> peers
198.82.1.203: timed out, nothing received
***Request timed out
ntpq>

I'm not sure I'm using this right but it seems not matter what I try ntpq does nothing and it always worked in the past. At first I thought it might be due to the round trip transit time between here and the satellite which probably add a quarter of a second? But it seems to me that I've seen some long delays in the ntpq data at times although that's not typical, normally more like
.160 [s/ms?].
