?
I have been reading all the emails back and forth on this. I am new to the list 
but have provided my server to the pool for about a year. I view the goal of 
pool.ntp.org to provide time to the public(This is my view of it). When I say 
public I mean mostly end users and people who do not care about being off by a 
couple seconds(again my view). Do we know how many users of the pool only query 
one server? Here is an idea I had, Why not do away(CNAME to the main pool) with 
the country codes and then have the 0,1,2 etc zones be only high quality 
servers. For the general public using the pool.ntp.org zone and getting 
reasonably close time is fine. For those that want something more they can 
query the unique zones(0,1,2 which should be unique but I guess at this point 
are not).
Just my 2 cents worth please correct any errors that I missed
Thanks,
Will

Subject: [time] subzones of the pool and similar stuff





I think I'm done wandering around the discussion about the subzones
and similar stuff.  It doesn't look like it is leading anywhere
useful. I think it has also become very unfocused.

Try try and bring things back into focus, here is a summary of my
thoughts on the NTP pool project:


TOP PRIORITY:

* increase the number of servers in the pool


VERY IMPORTANT:

* The 0, 1, and 2 zones *MUST* be orthogonal.  That is, at any give
  time, a pool server MUST NOT be in more than one of them.


* We should create a 3 and 4 zones so that false tickers can be
  detected.  Remember: pool servers are often not that reliable over
  long periods of time, so it is quite possible to pick up a couple of
  servers that turn out to be false tickers after a couple of months.


* All zones must have a minimum of 3-5 servers in them so that some
  server doesn't end up being overloaded.  Filling these zones from
  the global pool is *FAR* better than leaving them nearly empty.


GOALS:

The goal of the NTP pool project should be to have a simple, easy to
use way, of getting reasonably good time.



I think it is very easy for us to provide time in the 50-200ms
accuracy range, and therefore we should.  I think it would be very
hard for us to provide time in the 5-20ms accuracy range, therefore we
shouldn't.  I think aiming for just "sub second" accuracy won't save
us any work because any NTP server that can't provide 50-200ms
accuracy almost certainly isn't reliable enough to provide 500-1000ms
accuracy.  There is a "sweet spot" at around 50-200ms.


I think geographic distances are a poor approximation of network
distances, but good enough to be usable.

If people think that this is not the case, then we should immediately
"retire" the continent and country zones by making them a CNAME to the
global zone.


I think that timezones make a useful geographical division of the
world because it is almost always know to configure scripts and
because it often reflects political boundaries when those boundaries
are useful.
