I disagree.

I strongly disagree.

I have strongly disagreed for a long time, so I'm just going to repeat
myself.

The goal for the region sub-zones (europe, jp, us, etc.) should be
that they contain NTP servers that are useful *for NTP clients* in
those regions to use.  They should not be limited to only *NTP
servers* that are in those regions.

If there aren't enough NTP servers in those regions, then those zones
should be filled with nearby regions.

Also, timezone specific zones should be created as another way of
dividing up the pool in an easy to configure way.  It makes very
little sense to give Portugal and Russia the same kinds level of
divisions.  This also gives a greater division of the pool, allowing
for the load to be spread more evenly.


These zones need to be set up *now* so that they can start being put
into configurations and setup scripts.  It make take years before
Greece has enough NTP servers to fully support 4 independant zones
with no fall-backs to wider zones, but we want people to start
configuring their NTP clients that way today.

Three servers can *detect* a false-ticker, but not *correct* for one.
Granted, most likely either of the other two good tickers will be good
enough to satisfy the NTP pool's goals, but I think it is reasonable
for the pool to support 4 servers.
