The pool.ntp.org project is a big virtual cluster of timeservers providing reliable easy to use NTP service for millions of clients.
The pool is being used by millions or tens of millions of systems around the world. It's the default "time server" for most of the major Linux distributions and many networked appliances (see information for vendors).
Because of the large number of users we are in need of more servers. If you have a server with a static IP address always available on the internet, please consider adding it to the system.go up

There’s a new forum for discussion related to the NTP Pool at community.ntppool.org. Please come join us. There are a couple interesting threads about the recent leap second and lots of empty space for your questions or suggestions. :-)
The NTP Pool mailing lists are generously hosted on lists.ntp.org on the Network Time Foundation infrastructure. Those servers moved this summer and it’s been a bit of “rough seas” since. Over the summer hundreds of people got unsubscribed because mail deliveries were failing and the lists were bouncing all mails for a while in the second half of December.
We’ll keep having the mailing list, too. In particular for people new to the project having us build out the new forum will be better (search, better access to archives, getting more mail in your email inbox is optional, etc).
Happy new year!

Since last Tuesday some countries have seen an excessive number of queries to the NTP Pool.
Hopefully the Snapchat developers will fix it soon (and sign up for a vendor zone!).
(Yes, the first link is to a new forum).

The IETF has published a new version of NTP Best Current Practices documenting learned best practices on how to run NTP servers and clients.
If you know a little about the NTP protocol reading it will be a quick way to learn more about how it works “in the wild” (including on your own systems).
Some of it is specific to the “reference” ntpd implementation, but much of it will apply to other clients or servers, too.

- The NTP Pool DNS server uses GeoIP data from MaxMind to help choose an NTP server from the Pool.
- Meinberg, makers of incredibly fine time server systems.
- The Public servers abuse and the Fixing the NTP server abuse problem threads on the comp.protocols.time.ntp newsgroup have caused this project to be started.
