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

Introduction

Active Servers

As of 2019-10-16

O projeto pool.ntp.org é um grande cluster virtual de servidores de tempo fornecendo um serviço NTP confiável e fácil de usar para milhões de clientes.

A pool está sendo usada por milhões ou dezenas de milhões de sistemas por todo o mundo. É o "servidor de tempo" padrão para a maioria das distribuições Linux e muitos appliances de rede (veja informação para fabricantes).

Por causa do grande número de usuários nós estamos precisando de mais servidores. Se você tem um servidor com um endereço IP estático sempre disponível na Internet, por favor considere adicioná-lo ao sistema.

O projeto é mantido e desenvolvido por Ask Bjørn Hansen e um grande grupo de contribuidores na lista de discussão. O código está disponível.

Hospedagem e largura de banda para os servidores "hub" são atualmente fornecidos por Packet e NetActuate.

    NTP Pool servers on Kubernetes on Packet

    Packet is awesome.

    When we started planning our recent unplanned server move, we investigated options for having not one, but two sites, for the “hub” systems for the NTP Pool. With 4000 NTP servers and hundreds of millions of clients using the system, it really should be a given!

    Evaluating our options on a ridiculously short timeframe, Packet stood out as an interesting choice, though we were a little apprehensive at first if their setup would be too unusual compared to more familiar options.

    After a quick chat with some of the friendly staff at Packet, we were off to the races to see if we could get everything migrated in less than a week of nights and weekends. If we could, we’d be able to move the physical servers the following Sunday without downtime to any critical services, and get us closer to having proper redundancy.

    Working with the Packet system has been fascinating and extremely productive. Despite having done this sort of work for several decades, it was a surprise how mixing familiar capabilities, APIs and abstractions opened new ways for quickly building and managing powerful, reliable and scalable infrastructure.

    New Account Features

    The beta site has been updated with new features for managing the accounts. Until now each server had to be associated with just one user login. In the new system servers are associated with an account that can have multiple user logins. If you can, please try it out and post bug reports or suggestions in the development forum or via email.

    NTP Pool servers hosted at NetActuate

    The NTP Pool consists of (as of this writing) more than 4000 NTP servers provided by the community, about 40 DNS servers and a good handful of “hub servers” running the website, databases, monitoring (for NTP, DNS, etc) and a bunch of other software to keep the system going. This spring we learned that the facility the systems were in was being decommissioned and we needed to find other arrangements, quickly.

    GPS rollover

    As you might have seen in the news or from the US CERT, there’s an internal counter in the GPS messages that will “rollover” this week. Poorly implemented GPS receivers might lose track of time because of this. Many servers in the NTP Pool are using GPS signals to set the time, either directly or indirectly from another server that listens for GPS signals. The expected impact on users of the NTP Pool is very little or none at all.

    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.
