Apologies, I sent a reply to your personal email by mistake - 
Thunderbird has it as default.

Hi Harlan,

Version is 4.2.4p (yes, I know. It's the same version I've been talking 
about and I cannot upgrade it unfortunately).

When running ntpq -p I've got this

xxxxxxx-2:/etc# ntpq -p
      remote           refid      st t when poll reach   delay   offset 
==============================================================================    .INIT.          16 u    -   64    0    0.000    0.000 

  xxxxxxx-2:/etc# ntpdate
20 May 23:30:11 ntpdate[16690]: no server suitable for synchronization found

(hopefully it will be better aligned on your news reader!)

The same works from other networks.

If I keep pinging different pools, I can find another NTP server which 

Question: if I use the pools and for some reason the current server is 
not reachable, when the server is changed will NTP update and start 
using the new server instead? Or will NTP needs to be restarted?

In other words: if my server boots up when a non-reachable server is 
linked, will it keep the same unreachable one till next reboot?

Thank you!
