NTP Pool News Archive NTP Pool servers on Kubernetes on Packet Sep 6, 2019 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.

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 Aug 27, 2019 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.

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.

Oliver Nadler has another tutorial covering non-Ubuntu, too. NTP Pool Forum Jan 1, 2017 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. :-) Continue Reading → Excessive load on NTP servers Dec 19, 2016 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. Continue Reading → Equipment failure Nov 29, 2016 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 Nov 4, 2016 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). Continue Reading → System status page Aug 27, 2016 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 ).
