Quick update – 10 August 2016

Filed under: clients,project status,stats @ 02:18 UTC

Apologies, it has been a while since I published a blog update. The front page of our web site still has a problem, but we are making progress on our projects. A look at OGR-28: 42,000 participants. 900 days. 31 BILLION (I know!) Gnodes checked. 20% completed. We can still complete it by New Year if each of us gets a few friends to join in!

RC5-72 has been in progress for 5,000 days as I write. There is still a long way to go, with only just over 4% of the work completed. To have the help of 120,000 participants is amazing. Thank you for all of your contributions.

Have you downloaded new dnetc client software lately? There are a raft of improvements in the last couple of versions, including speed-ups on some platforms (the latest came out of pre-release two months ago). Moo!


2 year OGR-28 anniversary update!

Filed under: project status,stats @ 22:43 UTC

Dear friends,

We’re happy to announce a new client software version, 2.9112.521, for all major operating systems. These are available on the pre-release page: We would be happy for you to check them out and give us your feedback! Among the improvements are better GPU support, OpenCL on more platforms, and a new AVX2 core for RC5-72 contributed by Yasuhiro Katsui which runs 3.6x faster than the previous code. If you find any issues, please report them to us at We expect to move the build 521 clients to release status after a short time.

As of this writing, we have just passed the second anniversary of the OGR-28 project. With over 36,000 contributors from around the world, we have completed more than 14% of the work necessary to prove the Optimal Golomb Ruler with 28 marks. You can track our progress on, where we’ve recently restored the popular keyrate graphs, which show changes in our network’s speed over time. This one is for OGR-28:

As you might have noticed above, many of our websites are also now available via https. Feel free to update your bookmarks.

We are grateful for all of your contributions. Please tell your friends about our projects, and watch those keyrate graphs go up!



Quick update – January 12 2016

Filed under: project status,stats @ 23:52 UTC

Dear friends,

With nearly 35,000 volunteers and 13.38% of the search space completed, we’ve just started on a new OGR range today (8-x) and so daily stubs completed will be higher. We’re still struggling with our web site, but glad that you’re here with us. Keep telling your friends. We need all the help we can get. Moo!


Keymaster temporarily back online

Filed under: keyservers,stats @ 02:00 UTC

Well, after nearly 12 days we’ve managed to get the old keymaster hardware back online. The problem ended up being some failing RAM, though the symptoms weren’t immediately obvious as that. Although we are currently still operating on the old hardware, we are planning to transition to newer hardware tomorrow. The newer hardware was shipped last week during the outage and is still in the process of being racked and powered up.

We do not expect tomorrow’s transition off the old hardware to be externally visible since our proxy network will have caught up and buffered enough work for the brief outage. Stats will have a multi-day gap during the time we were offline, but we expect that the statistics totals for 2015-07-22 will reflect a significantly higher-than-normal amount of work due to all of the backlogged data that had been buffered.

Additional measures are being made to ensure that an outage of this duration does not happen again.

Thanks again for your patience! ]:8)


Keymaster interruption again

Filed under: keyservers,stats @ 04:28 UTC

We are experiencing another hardware issue with our central keymaster, and we do not yet have an estimate for it to be brought back online. However, our proxy network will continue to buffer completed work until the keymaster can be brought back online. Stats will also be delayed until that occurs. More information will be posted as it becomes available. Thanks for your patience! ]:8)


Keymaster interruption

Filed under: keyservers,stats @ 02:37 UTC

We experienced some hardware issues with our keymaster server today, possibly due to a mechanical issue. It had a few hours of downtime on 2015-05-16 causing work to become backlogged and buffered on our keyserver network, which means that the stats for that day will be significantly lower than usual, however tomorrow’s stats should include all of that backlogged work. Newly submitted work is continuing to be processed without delay at this point.

Although the keymaster is back online for the moment, we are continuing to do remote hardware diagnostics. It sounds likely that we may need to replace a system case fan however. Thanks for your patience and support!


Stats maintenance [resolved]

Filed under: stats @ 22:38 UTC

We’re currently in the process of doing some backend database, webserver, and OS upgrades to our stats servers, so we’ve temporarily disabled access to it until we’re done. Once we’ve verified that everything appears to be working, we’ll brings the stats pages back online. No project data will be lost during this maintenance, and we’ll restart stats processing once it’s done. Thanks for your patience.

Update: This maintenance has now been completed and everything is back to normal.


Stats server move completed

Filed under: stats @ 01:41 UTC

standard and deviation, before the move

As previously announced, we had to move our stats servers to a new hosting location due to changes at our old hosting provider.  Logistically it was quickest and easiest for us to simply physically move the two servers to their new location in Houston, so we completed that move today.  Zone file entries have been updated, so should now take you to the new location once any cached DNS entries have been propagated.

The downtime was a little longer than planned because of an unexpected routing failure that began at our old location earlier than our planned start of the move.  We also waited until stats has fully processed all of its backlog before officially publicizing its new IP address at its new location.

Part of the transport occurred by private plane, and although the outbound flight was tracked on FlightAware, the return flight was unfortunately not publicly visible due to an air traffic control limitation.

No dnetc work submitted during the downtime was lost, and our stats pages should now fully reflect the last day of work.



Stats server downtime for relocation

Filed under: stats @ 15:20 UTC

Our stats server is currently offline as we prepare it for relocation.  We expect it to be back online tomorrow around 2014-05-11 at about 22:00 UTC but it is possible that we may need to delay its restart time.

During the downtime we will be physically relocating our servers 160 miles, from Austin, TX to a new hosting location in Houston, TX offered by FlightAware.  Part of the transport will be conducted by private plane, which might be visible on the FlightAware flight tracking website around 2014-05-11 at 17:00 UTC.

We’d like to thank Midas Green Tech in Austin, TX for the use of their hosting facilities over the years, but their business is transitioning away from physical hosting and towards virtual hosting so our move was an unfortunate necessity. If you are in need of any cloud hosted services, we encourage you to check out their offerings and mention that  you heard about them from

As always, all dnetc work transmitted during the downtime will be fully counted once our stats website is brought back online.


[resolved] statsbox maintenance

Filed under: stats @ 04:30 UTC

We’ve taken statsbox temporarily offline for some minor system updates.  It should be back online before the next statsrun.  As usual, there will be no impact to stats or our proxy network during this downtime.

UPDATE: It is back online now and no problems were encountered during the maintenance.
