pool.ntp.org projesi güvenilir, kolay kullanılır, milyonlarca kullanıcıya NTP hizmeti veren büyük sanal zaman sunucularının kümesidir.
Havuz dünyada milyonlar hatta on milyonlarca sistem tarafından kullanılmaktadır. En popüler Linux dağıtımlarının bir çoğunun ve ağ cihazlarının bir çoğunun varsayılan zaman sunucusudur (tedarikçiler için bilgi).
Çok fazla kullanıcı olması sebebiyle daha fazla sunucuya ihtiyacımız olmaktadır. Eğer sabit IP adresi olan kesintisiz internetli bir bilgisayarınız varsa sistemimize eklemeyi düşünebilirsiniz.
Projenin bakımı ve geliştirilmesi Ask Bjørn Hansen ve posta listesindeki büyük bir gurup katılımcı tarafından yapılmaktadır. Kod'a github'dan ulaşabilirsiniz.
"Hub" sunucularının hosting ve bant genişliği şu anda Packet ve NetActuate tarafından sunulmaktadır.

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. The NTP Pool monitoring system will detect any systems that are wildly off and have them removed from DNS responses within typically 10-20 minutes.
Most servers would also recognize that the “jump” in time from a potentially misbehaving GPS clock is too large and ignore it (the time would be set back to August 1999, most likely).
Most importantly, reasonably well written clients will poll 3 or 4 IPs and ignore the one that’s an outlier by decades, recognize that the time returned is many years older than the earliest possible manufacturing date of itself or that the jump in time is too large and again ignore it.
The time of the rollover is midnight UTC on April 7 (so late afternoon April 6th in California or the morning of April 7 in Asia). We will be checking the NTP Pool monitoring data for any signs of problems through the day.

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.
