Active Servers

As of 2019-03-27

pool.ntp.org 是一个以时间服务器的大虚拟集群为上百万的客户端提供可靠的 易用的 网络时间协议(NTP)服务的项目

NTP池正在为世界各地成百上千万的系统提供服务。 它是绝大多数主流Linux发行版和许多网络设备的默认“时间服务器” (请参阅 服务供应商的信息).

由于用户的数量庞大,我们需要更多的服务器。如果您有一台具有静态IP地址并且一直处于联网状态的服务器,请考虑 将其加入我们的系统.

这个项目由 Ask Bjørn Hansen邮件列表中的一大群贡献者开发与维持. 这个系统的源代码可 在此获取.

“总线”服务器的主机和带宽由 Develooper网Phyber 通讯网提供.

    How to Configure NTP for Use in the NTP Pool Project

    Daniel Ziegenberg wrote a tutorial for Digital Ocean on configuring NTP for the NTP Pool on Ubuntu.

    Oliver Nadler has another tutorial covering non-Ubuntu, too.

    NTP Pool Forum

    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!

    Excessive load on NTP servers

    Since last Tuesday some countries have seen an excessive number of queries to the NTP Pool.

    After much detective work on nanog (conclusion) and the #NTP IRC channel it was determined to be a buggy Snapchat app update.

    Hopefully the Snapchat developers will fix it soon (and sign up for a vendor zone!).

    (Yes, the first link is to a new forum).

    Equipment failure

    A network switch failed causing an outage for the management system and the NTP Pool website. The DNS and NTP services should only be minorly affected, even if the outage lasts a little while.

    I’ll update status website with updates.

    NTP Best Current Practices

    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.
