pool.ntp.org: public ntp time server for everyone

Introduction

Active Servers

As of 2017-01-21

pool.ntp.orgは、タイムサーバの大きな仮想クラスタであり、何百万ものクライアントへ使いやすい安定したNTPサービスを提供するプロジェクトです。

世界中の数百万~数千万のシステムがこのプールを使用しています。 主要なLinuxディストリビューションや多くのネットワーク機器(ベンダ向け情報)の殆どではデフォルトのタイムサーバとしてこのプールを使用しています。

非常に多くのユーザが使用しているため、もっと多くのサーバが必要です。 もし常時インターネットに接続していて固定のグローバルIPアドレスを持つサーバをお持ちなら、システムに参加することを検討して下さい。

このプロジェクトはAsk Bjørn Hansenメーリングリストの多大な貢献によって開発・維持管理されています。 ソースコードは公開されています。

"ハブ"サーバのホスティングや帯域幅の情報は現在、DevelooperPhyber Communicationsによって提供されています。

    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.

    System status page

    Thanks to the kind folks at statuspage.io we now have a system status page. It’s also available at an alternate domain.

    Most of the data is updated manually, so it won’t be any better than the busy humans can manage, but it’ll be a better system for giving system updates than posting here (or on the dicussion mailing list).

    Update Whoops, I completely forgot that ntppool.org is in the HSTS preload list.

    The site was working for me in the browsers I tested. I’ve contacted statuspage.io about getting a TLS cert added, in the meantime ntppool.statuspage.io works.
