Introduction

pool.ntp.org는 수백만 클라이언트들에게 안정적이고 사용하기 쉬운 커다란 가상의 시간 서버 클러스터를 제공하는 프로젝트입니다.

전 세계에 있는 수백만, 수천만의 시스템이 이 풀을 사용하고 있습니다. 대부분의 주요 리눅스 배포판과 많은 네트웍 설비들이 이 풀을 내정된 시간 서버로 사용하고 있습니다. (제조사를 위한 정보 참고).

많은 사람들이 사용하므로 서버가 더 필요한 상황입니다. 귀하가 만약 고정 IP 주소와 언제나 인터넷에 연결 되어 있는 서버를 소유하고 있다면 시스템에 합류하는 것을 고려해 보십시오.

이 프로젝트는 Ask Bjørn Hansen 과 메일링 리스트 에 있는 대단한 기여자들에 의해 개발, 관리되고 있습니다. 소스 코드는 공개되어 있습니다.

"허브" 서버 호스팅과 대역폭은 현재 Develooper와 Phyber Communications, YellowBot에 의해 제공되고 있습니다.

  Website updates and translations

  As announced some days ago on the pool-dev mailing list, yesterday I moved the "manage your server" section to a separate site. This helps keep the main site fast and made it easier to make all connections to that site encrypted.

  Today the NTP Pool site got some changes to run better and faster. In the process there was 10 minutes of downtime late Tuesday (pacific time) and through much of the day Wednesday some pages might have loaded in a language that wasn't your usual preference.

  Speaking of languages, the website can (always) use help with translations. On the beta site I enabled some of the partially translated languages to show up. Japanese was just added there today thanks to Taro Yoshimoto.

  Translations of languages not on the list at all are of course also welcome.

  Continuing IPv6 deployment

  World IPv6 Day is over, but we'll continue to serve AAAA (IPv6) records for 2.pool.ntp.org (and 2.europe, 2.fedora, 2.debian, etc).

  So far no problems have been reported, even the servers going through IPv6 tunnels seem to work fine.

  We already have almost 200 IPv6 servers in the pool; though that's less than 10% of all the pool servers and they're mostly in a handful of countries versus the wide deployment we have for IPv4.

  The pool system is tracking, but not yet showing separate stats for IPv6 servers by default. (You can however "hack" the graph URLs to show them by adding -v6 to the file name, for example the European counts.

  Below is the graph for the total number of IPv6 servers in the pool.

  Monitoring of some servers temporarily suspended

  While the system is rebuilding some internal statistics, monitoring of some of the IPv4 servers in the pool have been suspended. They'll be reactivated in about 6 hours. All servers with IDs below 8500 are being monitored again after a break of a couple of hours.

  In addition all IPv6 servers are being monitored now and are slowly increasing their scores for inclusion in the "2." pool!

  Experimentally enabling IPv6

  If you are following the pool mailing lists you'll have seen that the last days have carried a flurry of activity as new code for IPv6 support (and distributed monitoring) has been tested on the "beta pool" site.

  June 8th is World IPv6 Day where many sites small and big will enable the IPv6 protocol for the day to help test everyones IPv6 readiness.

  Here at the NTP pool we are today enabling monitoring of IPv6 servers; and over the next 12 hours we will start in a limited fashion to serve AAAA (IPv6) DNS records to clients asking for them. Right now the pool site is enjoying a brief break while the new code and database updates are being deployed.

  For now this will only be on the "2.pool.ntp.org" zone; but unlike Google, Facebook and most other sites we are not planning to turn this off again on June 9th.

  Brief web outage

  One of the database replicas had some corruption; so I took down the primary database briefly to run some consistency checks there, too. This is taking down the NTP Pool website and delaying some of the monitoring.

  Everything will be back shortly.
