Sub-optimal monitoring performance

Fri, 25 Apr 2008 03:55:13 +0000

Early this morning (PST) we had a few hours of "sub-optimal" performance on the monitoring server. A hundred servers or so were marked "bad" and got unnecessary warning mails because of it. users of the pool should not have been impacted. Work is in progress to permanently improve on this.

Outage yesterday

Sat, 29 Dec 2007 22:03:37 +0000

We were upgrading the servers that the pool web site is running on yesterday and had an outage for a few hours. It should all be back to normal now.

The upgrade was (mostly) about getting all our servers up from RHEL 3 to version 5 (before we had mostly RHEL3 boxes and a few with 4 and 5 ...). Now when they are all the same it's easier for us to manage the configuration across all the boxes and soon we'll have some more high availability things setup for the pool system. Long term the goal is to get more of the infrastructure completely distributed, but the website (for showing stats etc) will likely still be in just one place.

Plan for IPv6 Support

Thu, 18 Oct 2007 06:50:47 +0000

A relatively frequent question I get is "when will the pool support IP v6".

It's on the "road map", but not too high up on the list. Months ago I wrote up the current plans on the NTP Pool wiki.

Speaking of the wiki - eventually I'll get that moved over to the NTP Public Services Wiki.

The Pool is 100% on the new DNS system

Tue, 02 Oct 2007 09:25:54 +0000

With some assistance of Guillaume Filion the fifth pool.ntp.org is now running the new DNS software, too. It's located in Germany. We have a few more servers offered by volunteers ready to be setup and we'll work on that over the next week or so and then we'll experiment with how best to use them to get the best possible performance for the pool users.

The difference is that now pool operators shouldn't see "spikes" in traffic, unless a big ISP caches the DNS entry and gives it out to many many many clients. If that happens we'll experiment with adjusting the TTL of the served records (The "TTL" is the time-to-live, the time the data should be cached by the end-user nameserver).

DNS status

Fri, 28 Sep 2007 09:14:35 +0000

We deployed the new DNS system to 4 out of the 5 pool.ntp.org nameservers. We have several new systems that volunteers have offered ready to be setup, but no time to configure and test them yet. Hopefully it will be done within a week or so...

There's a description of the new system on the DNS page on the wiki.

We've noticed an issue with the new system that it seems too eager to send traffic to the high bandwidth systems rather than the low-bandwidth ones. I am looking into it, although not with too much urgency as none of the high-bandwidth server operators have gotten more traffic than they can handle.

More Meinberg equipment donated!

Wed, 26 Sep 2007 08:46:11 +0000

On hearing how many people had sent in applications for the equipment giveaway our friends at Meinberg offered us some more equipment!

For diversity from the GPS units the extra 3 systems will be DCF77 cards (PCI or PCI-Express).

Since DCF77 only works in Europe we're planning to give them out there and then pick hosts in the rest of the world for the GPS units.

Also - in particular one of the locations having offered to host the LANTIME server is ideal as a future home for the pool system in general, so the LANTIME (also donated by Meinberg) that I'm currently using will also be sent out (location to be determined).

NTP Pool Weblog

Wed, 26 Sep 2007 08:07:17 +0000

I've setup a weblog for posting news about the NTP Pool project. This will be much nicer and hopefully make it easier to get slightly more frequent updates. The old process had me updating the list of news by editing HTML on the site (or rather, edit in my development copy, commit to subversion and then run the deployment to the site).

I've "imported" all the old news into the weblog and soon I will update the main site so it pulls the recent news automatically.

Big news: Meinberg giveaway, new pool site

Thu, 06 Sep 2007 08:04:43 +0000

Three awesome news items today:

1: We're announcing the great Meinberg GPS time equipment giveaway. Over the next months we're (thanks to Meinberg) giving away thousands of dollars worth of high quality time-keeping devices.

2: We got a brand new design and layout on the pool site! Many more updates are coming.

3: The pool is the default ntp service in several of the big Linux distributions (Fedora, Debian, RHEL, CentOS and many more). For this reason we really really need more servers to help with the traffic. Hopefully the equipment giveaway will help on this. Please mention it in your weblog or wherever else appropriate.

On a related sidenote we've started alpha-testing a new system for distributing traffic to the servers more evenly and with much less "spikes" in the traffic.

Close to 1000 servers; Meinberg donation

Thu, 22 Feb 2007 08:03:23 +0000

We are getting close to one thousand active servers in the pool system! The pool system has gotten a major software upgrade, most notably safely letting the server operators do more without having to involve me. Please email ask@develooper.com if you see anything odd.

Coming up on the todo list is revamping the monitoring system. With the help of a donated time server generously donated by Meinberg I am working on a better and distributed monitoring system.

The NTP Pool project now has a wikipedia entry.

Separate "global zone" and "all servers" count

Mon, 24 Apr 2006 08:01:45 +0000

The system has been changed a little so we now have separate counts for "all servers" (almost 700 servers!) and servers in the global pool (+600 servers!). The global is by far the busiest, as most users don't pick a country or continent zone.

I've also done some more measuring and estimating of the client population and my best guess is that somewhere between 2 and 6 million client systems are using the pool.

Vendor information available

Sat, 22 Apr 2006 07:59:01 +0000

The new information for vendors page is up! Please let me know if your operating system/appliance/software vendor is using the NTP Pool but isn't using a vendor zone.

Reached 500 servers - Welcome Slashdot

Sun, 15 Jan 2006 07:58:11 +0000

Welcome Slashdot readers. The Slashdot story was that we had reached 500 active servers, but since the story was posted another 50 or so servers joined us! This is great, thank you everyone. The only way we can keep the load on each server reasonable is by adding more servers quickly. If you can, please join. More than 500 servers in the pool might sound like a lot, but our best guestimates puts the number of clients at either hundreds of thousands or millions of computers.

Self-service "Add your server" system

Wed, 10 Aug 2005 07:57:13 +0000

You can now add your NTP servers (and only your own, please) via the new web interface. Please email me if it doesn't work as expected.

Zone browser

Tue, 09 Aug 2005 07:56:11 +0000

You can now browse the available zones. Also, I split up the front page into a few smaller pages. I've fallen a little behind on adding servers. I'll catch up soon and get the self-service web interface done.
