Primary time scale failure at NIST Boulder campus; significant impact on NTP services
Dec 20, 2025, 12:18:52 PM (yesterday)
Dear colleagues,
In short, the atomic ensemble time scale at our Boulder campus has failed due to a prolonged utility power outage. One impact is that the Boulder Internet Time Services no longer have an accurate time reference. At time of writing the Boulder servers are still available due a standby power generator, but I will attempt to disable them to avoid disseminating incorrect time.
The affected servers are:
time-a-b.nist.gov
time-b-b.nist.gov
time-c-b.nist.gov
time-d-b.nist.gov
time-e-b.nist.gov
ntp-b.nist.gov (authenticated NTP)
No time to repair estimate is available until we regain staff access and power. Efforts are currently focused on obtaining an alternate source of power so the hydrogen maser clocks survive beyond their battery backups.

(84,707 posts)This is what it told me:
Short answer: yes, its a big deal operationally for NIST and some dependent systems but it is not a global time crisis, and most people and systems will not notice.
Heres how to think about it, from headline scary to practical impact.
What actually failed (and why it matters)
Whats down is NISTs Boulder-based atomic ensemble and Internet Time Services, not UTC itself.
Key points:
The atomic clocks didnt suddenly become wrong they lost their traceable reference and distribution path.
NIST is correctly taking servers offline to avoid distributing bad time, which is exactly what a responsible time authority does.
This is a power + infrastructure resilience failure, not a physics or clock-design failure.
The real risk here is silent time drift, which NIST is explicitly preventing by disabling the servers.
What is not happening
Lets kill a few scary interpretations:
❌ UTC is not broken
❌ GPS time is not broken
❌ Financial markets are not about to lose timestamp integrity
❌ TLS certificates are not going to globally fail
❌ The internet is not about to desynchronize
UTC is a composite international time scale maintained by the BIPM using data from dozens of labs worldwide (USNO, PTB, NPL, SYRTE, etc.). NIST Boulder is important but not a single point of failure.

(63,843 posts)I visited NIST a couple of times in my career. It's a cool place.
I worked in rubidium atomic clocks. It's a lesser standard than cesium or hydrogen masers, but it's still pretty accurate time wise, less than 1 microsecond/day error. H2 masers are several orders of magnitude better than that.

(938 posts)I would agree with your assessment. Situation not ideal, but also not the end of the world. It's one reason why UTC (and TAI) are "coordinated' between multiple nations, and their respective time reference systems.

I'm glad you at least identify it as chatbot-generated. But I can't understand anyone feeling it's okay to use when it's such an unethical and unreliable tool from an unethical (thieving and dishonest) company.

Or aware that chatbots can give different answers even when given the same prompt, just as AI image generators can offer endless different options from the same prompt.
Or aware of the illegal training data.
Or aware that chatbots aren't in any way intelligent and are just assembling responses based on the most likely next word or token, with no understanding of the meaning.

Personally, I'd accept any justification for removing AI-generated posts. They do not belong here, and serve no helpful purpose that isn't weighted with uncertainty which can never be dispelled.

(60,021 posts)genAI slop needed as an example. And a waiver for people who weren't aware something was AI-generated.
I recommended yesterday that FarPoint leave a Robert De Niro deepfake in her OP
https://www.democraticunderground.com/132299818
because she was going to complain directly to YouTube about it, and without leaving the video she couldn't show as clearly both which video it was and how much harm the deceit did. (The creator of that video has now added the synthetic-content label YouTube tells their creators they have to add, but the label wasn't there originally.) I also thought it was a useful example because the wording of a disclaimer in the YouTube descriptions suggested the creator is the same fraudster who earlier had fooled DUers with deepfakes of Jimmy Kimmel and Obama.

highplainsdem
(60,021 posts)knowledgeable or talented than they are. Some people using AI have clearly bought into the con that it's inevitable and that helps them shrug off all the problems with it. There's a hell of a lot of pressure to use AI tools, hype started and funded by the companies that profit from it or expect to profit from it.
But I don't have the impression we have any paid AI influencers here. Might have some DUers who have invested heavily in tech stocks and are praying the AI bubble won't burst.
And we seem to have some people who feel - wrongly, in my opinion - that even though the arguments against AI are valid, it still gives users enough of an edge that it should be used while we're fighting Trump. Which ignores the fact that the AI companies are on Trump's side, those AI tools are also ideal for surveillance of Trump's opponents, every public use of AI is in effect advertising for the AI companies to get more users, and those corporate-owned AI tools can be taken away completely or their use restricted at any time.

(60,021 posts)"It has come to my attention that a few clever and unscrupulous scammers have been posting music online while pretending to be me," says Parsons. "Theyve been gathering up streams, attention, and possibly even invitations to tea under my name These blatant infringements have nothing whatsoever to do with me.
"Let me be crystal clear I have not released these songs, authorised these songs, hummed these songs, or even accidentally sat on a keyboard and come up with anything resembling these songs.
"What a strange time we live in, when an imposter can write a tune, or have a toaster write it for him, slap my name on it as the artist, and then have a faceless algorithm give it life. While I admire their efficiency, I do find it rather disappointing that scammers are now turning their robotic identities against musicians everywhere.

"This tomfoolery doesnt just confuse listeners, it dilutes the talent of those artists, muddles their identity, and chips away at the integrity that takes years, or in my case, decades, to build. I spent most of my life finding my voice in the music industry, and Id like to keep it human, thank you very much.

(31,658 posts)lot of people don't know about his full career in music -
Parsons was the sound engineer on albums including the Beatles' Abbey Road (1969) and Let It Be (1970), Pink Floyd's Dark Side of the Moon (1973), and the eponymous debut album by Ambrosia in 1975. Parsons's own group, the Alan Parsons Project, as well as his subsequent solo recordings, have also been commercially successful. He has been nominated for 13 Grammy Awards, with his first win occurring in 2019 for Best Immersive Audio Album for Eye in the Sky (35th Anniversary Edition)
