NTP Servers in New Zealand

There is a pool of servers at nz.pool.ntp.org, which provides Round Robin DNS access to publicly accessible NTP servers that have agreed to be part of the pool.

Many ISPs have NTP servers for their customers:

  • ntp.iprolink.co.nz
  • ntp.iconz.co.nz
  • tk1.ihug.co.nz to tk3.ihug.co.nz
  • time.paradise.net.nz

Some universities have publicly accessible servers:

  • ntp.public.otago.ac.nz (Please notify before using)
  • ntp.massey.ac.nz

For a long time Waikato University had public NTP servers. They are still available but no longer publicly accessible.

Stratum 1 Servers in New Zealand

You shouldn't synchronise to a stratum one server for your small network -- if everyone did that then the server would need too much bandwidth. The difference in accuracy between synching to a stratum 1 server and a lower stratum server is negligible! more

.nz Registry Services

There are three stratum 1 NTP servers provided by .nz Registry Services (NZRS) for network operators based within New Zealand. more

  • s1.ntp.net.nz in Albany connected to FX?.
  • s2.ntp.net.nz in Auckland connected to ICONZ and APE.
  • s3.ntp.net.nz 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

The Measurement Standards Laboratory

The standard for time in New Zealand is maintained by the Measurement Standards Laboratory, part of Industrial Research Limited. MSL runs several public NTP servers that are referenced to UTC(MSL).

  • msltime.irl.cri.nz
  • msltime1.irl.cri.nz
  • msltime2.irl.cri.nz

They are FreeBSD-based servers that are directly connected to their master HP5071A caesium clock. more

Stratum 1 Servers in other countries

United States

The US National Institute of Standards and Technology (NIST) operates several publicly accessable stratum 1 time servers 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. more

  • nist1.symmetricom.com San Jose, California
  • nist1-sj.ustiming.org San Jose, California
  • nist1-la.ustiming.org Los Angeles, California
  • nist1.aol-ca.symmetricom.com Mountain View, California

The US Naval Observatory (USNO) operates several stratum 1 time servers from it's Alternate Master Clock Facility (AMCF) at Schriever Air Force Base, near Colorado Springs, on the same site as the GPS Master Control Station. These servers are referenced to UTC(USNO). more

  • tick.usnogps.navy.mil
  • tock.usnogps.navy.mil

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). To use these servers, you need to register via email. more
