-You shouldn't synchronise to a stratum 1 server for your small network -- if everyone did that then the server would need too much bandwidth. For example. NetGear hard-coded a public
[NTP] server into some of their consumer products, which eventually ended up using hundreds of Mbits/second of the university's bandwidth, even after they were forced to shut down the server.
-
-The difference in accuracy between syncing to a stratum 1 server and a lower stratum server is negligible.

-!!! NewZealand
-
-! .nz Registry Services
-
-There are [three stratum 1 NTP servers provided by .nz Registry Services (NZRS)|http://ntp.net.nz/] for network operators based within New Zealand.
-
-* <tt>s1.ntp.net.nz</tt> in Albany connected to [FX].
-* <tt>s2.ntp.net.nz</tt> in Auckland connected to [ICONZ] and [APE].
-* <tt>s3.ntp.net.nz</tt> in Wellington connected to [FX] and [WIX].
-
-All three are Symmetricom S300 NTP servers, each connected to a differential GPS antenna on the roof and each with a rubidium oscillator to provide a stable clock in the event of an issue with the GPS signal. [more|http://ntp.net.nz/architecture/]
-
-! The Measurement Standards Laboratory
-
-The standard for time in New Zealand is maintained by the [Measurement Standards Laboratory|http://msl.irl.cri.nz/], part of [Industrial Research Limited|http://irl.cri.nz/]. MSL runs several public NTP servers that are referenced to UTC(MSL).
-
-* <tt>msltime.irl.cri.nz</tt>
-* <tt>msltime1.irl.cri.nz</tt>
-* <tt>msltime2.irl.cri.nz</tt>
-
-They are FreeBSD-based servers that are directly connected to their master HP5071A caesium clock. [more|http://msl.irl.cri.nz/services/time-and-frequency/ntp-server-information]

-!!! United States
-
-The US National Institute of Standards and Technology ([NIST]) operates [several publicly accessible stratum 1 time servers|http://tf.nist.gov/tf-cgi/servers.cgi] on the Pacific coast of the US. These servers are referenced to UTC(NIST) using the NIST Automated Computer Time Service (ACTS), a MoDem-based service established in 1988.

-
-The US Naval Observatory (USNO) [operates several stratum 1 time servers from its Alternate Master Clock Facility (AMCF)|http://tycho.usno.navy.mil/clocks.html] at [Schriever Air Force Base|WikiPedia:Schriever_Air_Force_Base], [near Colorado Springs|http://maps.google.com/maps?q=schriever+afb], on the same site as the [GPS] Master Control Station. These servers are referenced to UTC(USNO).

-* <tt>clock.fmt.he.net</tt> Fremont, California (GPS, Symmetricom NTS-150)
-
-!!! Australia
-
-The Australian National Measurement Institute (NMI) maintains the Australian time standard, UTC(AUS) using caesium and hydrogen maser standards. NMI [maintains a number of NTP servers which are referenced to UTC(AUS)|http://www.measurement.gov.au/Services/Pages/TimeandFrequencyDisseminationService.aspx]. To use these servers, you need to register via [Email
].
