On Wednesday afternoon, Anthropic experienced a brief but complete service outage that took down its AI infrastructure, leaving developers unable to access Claude.ai, the API, Claude Code, or the management console for around half an hour. The outage affected all three of Anthropic's main services simultaneously, with the company posting at 12:28 pm Eastern that "APIs, Console, and Claude.ai are down. Services will be restored as soon as possible." As of press time, the services appear to be restored.

The disruption, though lasting only about 30 minutes, quickly took the top spot on tech link-sharing site Hacker News for a short time and inspired immediate reactions from developers who have become increasingly reliant on AI coding tools for their daily work. "Everyone will just have to learn how to do it like we did in the old days, and blindly copy and paste from Stack Overflow," joked one Hacker News commenter. Another user recalled a joke from a previous AI outage: "Nooooo I'm going to have to use my brain again and write 100% of my code like a caveman from December 2024."

The most recent outage came at an inopportune time, affecting developers across the US who have integrated Claude into their workflows. One Hacker News user observed : "It's like every other day, the moment US working hours start, AI (in my case I mostly use Anthropic, others may be better) starts dying or at least getting intermittent errors. In EU working hours there's rarely any outages." Another user also noted this pattern, saying that "early morning here in the UK everything is fine, as soon as most of the US is up and at it, then it slowly turns to treacle."

Louisiana Governor Jeff Landry has a simple request for the Trump administration: Don't take our broadband money away.

Trump's Commerce Department rewrote the rules of the $42 billion Broadband Equity, Access, and Deployment (BEAD) grant program, forcing states to change how they spend money earmarked for expanding broadband access. The overhaul led states to reduce spending on fiber networks and increase spending on satellite—although not to the extent sought by SpaceX CEO Elon Musk, who is demanding more money for his Starlink network.

Since states are spending less on deployment, and the program still has the $42 billion allocated by Congress, what happens to the leftover amount after money is spent on deploying broadband networks? Amid speculation that the Trump administration wants to return that money to the US Treasury, Louisiana's Republican governor is worried that states won't be able to use the full $42 billion. It's possible that half or more of the $42 billion won't be used to expand broadband.

For millions of Spotify users, the "Wrapped" feature—which crunches the numbers on their annual listening habits—is a highlight of every year's end, ever since it debuted in 2015. NPR once broke down exactly why our brains find the feature so "irresistible," while Cosmopolitan last year declared that sharing Wrapped screenshots of top artists and songs had by now become "the ultimate status symbol" for tens of millions of music fans.

It's no surprise then that, after a decade, some Spotify users who are especially eager to see Wrapped evolve are no longer willing to wait to see if Spotify will ever deliver the more creative streaming insights they crave.

With the help of AI, these users expect that their data can be more quickly analyzed to potentially uncover overlooked or never-considered patterns that could offer even more insights into what their listening habits say about them.

Microsoft's Office 365 suite will soon incorporate AI models from Anthropic alongside existing OpenAI technology, The Information reported , ending years of exclusive reliance on OpenAI for generative AI features across Word, Excel, PowerPoint, and Outlook.

The shift reportedly follows internal testing that revealed Anthropic's Claude Sonnet 4 model excels at specific Office tasks where OpenAI's models fall short, particularly in visual design and spreadsheet automation, according to sources familiar with the project cited by The Information, who stressed the move is not a negotiating tactic.

Anthropic did not immediately respond to Ars Technica's request for comment.

Earlier this week, Ars spent some time driving the new Nissan Leaf . We have to wait until Friday to tell you how that car drives, but among the changes from the previous generation are door handles that retract flush with the bodywork, for the front doors at least. Car designers love them for not ruining the lines of the door with the necessities of real life, but is the benefit from drag reduction worth the safety risk?

That question is in even sharper relief this morning. Bloomberg's Dana Hull has a deeply reported article that looks at the problem of Tesla's door handles, which fail when the cars lose power.

The electric vehicle manufacturer chose not to use conventional door locks in its cars, preferring to use IP-based electronic controls. While the front seat occupants have always had a physical latch that can open the door, it took some years for the automaker to add emergency releases for the rear doors, and even now that it has, many rear-seat Tesla passengers will be unaware of where to find or how to operate the emergency release.

Last year, we reported on the discovery of an intriguing arrow-shaped rock on Mars by NASA's Perseverance rover. The rock contained chemical signatures and structures that could have been formed by ancient microbial life. Granted, this was not slam-dunk evidence of past life on Mars, and the results were preliminary, awaiting peer review. But it was an intriguing possibility nonetheless.

Now further analysis and peer review are complete, and there is a new paper, published in the journal Nature, reporting on the findings. It's still not definitive proof that there was water-based life on Mars billions of years ago, but the results are consistent with a biosignature. It's just that other non-biological processes would also be consistent with the data, so definitive proof might require analysis of the Martian samples back on Earth. You can watch NASA's livestream briefing here .

"We have improved our understanding of the geological context of the discovery since [last year], and in the paper, we explore abiotic and biological pathways to the formation of the features that we observe," co-author Joel Hurowitz, an astrobiologist at Stony Brook University in New York, told Ars. "My hope is that this discovery motivates a whole bunch of new research in laboratory and analog field settings on Earth to try to understand what conditions might give rise to the textures and mineral assemblages we've observed. This type of follow on work is exactly what is needed to explore the various biological and abiotic pathways to the formation of the features that we are calling potential biosignatures."

STARBASE, Texas —I first visited SpaceX's launch site in South Texas a decade ago. Driving down the pocked and barren two-lane road to its sandy terminus, I found only rolling dunes, a large mound of dirt, and a few satellite dishes that talked to Dragon spacecraft as they flew overhead.

A few years later, in mid-2019, the company had moved some of that dirt and built a small launch pad. A handful of SpaceX engineers working there at the time shared some office space nearby in a tech hub building, "Stargate." The University of Texas Rio Grande Valley proudly opened this state-of-the-art technology center just weeks earlier. That summer, from Stargate's second floor, engineers looked on as the Starhopper prototype made its first two flights a couple of miles away.

Over the ensuing years, as the company began assembling its Starship rockets on site, SpaceX first erected small tents, then much larger tents, and then towering high bays in which the vehicles were stacked. Starbase grew and evolved to meet the company's needs.

Hayden, a small town in the mountains of northwest Colorado, is searching for ways to diversify its economy, much like other energy communities across the Mountain West.

For decades, a coal-fired power plant, now scheduled to shut down in the coming years , served as a reliable source of tax revenue, jobs, and electricity.

Advanced driver assistance systems—also known as ADAS—come in a few variations. Blind spot monitoring, collision warnings, and emergency braking act like a second pair of eyes and ears, monitoring the car's environment to warn the driver, or possibly intervene, if a crash looks imminent. Other systems are better thought of as convenience features—things like adaptive cruise control and lane keeping , which relieve some of the burden of driving.

Among the newer of these is the traffic jam assist. It's a variant of adaptive cruise plus lane keeping designed for low-speed stop-start driving on limited-access highways, usually cutting out around 40 mph. But we're still talking about a so-called "level 2" system, where the human driver is responsible for maintaining situational awareness; even more advanced "level 3" assists exist— these allow the driver to completely disengage from the task —but are not the topic for today.

AAA recently put five (unnamed) ADAS systems to the test in the Los Angeles area, blessed as it is with dependable heavy freeway traffic. The testers went out together in morning and afternoon weekday traffic, covering the same routes simultaneously. The vehicles were driven an average of 342 miles (550 km) over 16.2 hours, with the ADAS operated according to each vehicle's user manual. And the cars were instrumented with cameras and GPS to record traffic conditions, behavior, and so on.
