When Russia began attacking Ukrainian data centers and telecommunication infrastructure, it apparently failed to prepare for possible retaliation. Now Russia’s digital services are facing widespread outages after Ukrainian drone strikes knocked out three of the largest data centers owned by Russian tech giant Yandex within several days.

Pro-Kremlin bloggers are warning that Russia’s centralized digital economy could collapse because the country is not prepared for the “data center war” it started, according to posts translated by the pseudonymous independent researcher ChrisO_wiki. The Russian commentators also suggested that Ukraine’s decentralized digital services could prove more resilient than Russia’s system if the countries continue trading such blows.

Russia initially launched a drone strike campaign targeting Ukrainian data centers and mobile phone networks in late September. The attacks temporarily disrupted Internet and cell phone service for up to 100,000 households in the Ukrainian capital of Kyiv and came as part of a broader long-range strike campaign that has involved Russian missiles and jet-powered drones hitting Ukraine’s power grid infrastructure, transportation hubs, and even residential apartment building blocks.

Google is releasing its second Fitbit tracker of 2026, offering fans of the aging Charge 6 a more refined option. The new Fitbit Edge slots right in between the Pixel Watch 5 and the Fitbit Air, featuring a compact screen and more health sensors than the Air. You won't get all the apps and features of the Pixel Watch 5, but the Edge is only about half as expensive.

The Fitbit Edge is essentially a new Charge 6, but it has more of a Pixel Watch aesthetic. Squish Google's smartwatch from the sides, and you've got the Edge. It has a pill-shaped 1.34-inch OLED touch display inside a slender aluminum frame that is rated IP68 (5 ATM) for water and dust protection. Google says the screen has 46 percent more viewable area compared to the Charge 6. It's very close in overall size to the Fitbit Air and uses the same magnetic charging puck.

The Edge works with Android or iPhones via the Google Health app, and it can run for about seven days on a charge. If the tracker is away from your phone, it can still follow your activity all week with support for seven days of full health data storage (or 30 days of basic data). However, the generous weeklong battery life does not include always-on display mode. If you turn it on, battery life drops to about two days, barely longer than the Pixel Watch 5.

No organization in the world operates more robots than Amazon. The company already has more than 1 million robots working in warehouses around the clock to make tens of millions of same-day and one-day package deliveries happen on a daily basis—and Amazon is poised to significantly grow that robotic fleet in the coming years as it establishes new factories to churn out increasingly more capable robot workers.

Despite deploying so many robots, Amazon is also the second-largest corporate employer in the world, with more than 1.5 million full-time and part-time human workers, according to its 2025 annual report. Amazon executives say that the growing robot fleet has eased the burden on its human workforce by taking on the toughest fulfillment center tasks that carry the greatest risks of physical fatigue and injury. But labor advocacy groups and independent researchers point to evidence suggesting that warehouse automation driven by AI is not all upside for the humans who work alongside robots.

“For the last 100 years, most of the automation that we've seen usually happens away from workers—you're taking that high-risk task away from the worker, and you're doing so in a way that is not physically proximate,” Brad Greenwood, professor of business at George Mason University, told Ars. “The rise of collaborative robots really changes that dynamic for two reasons: one is that it is physically proximate, and two, the robot has the ability to dictate the pace of work.”

Elon Musk is a very familiar figure to Ars readers, given his massive influence (for better and worse) on the technology sector over the last 20 years. Oscar-winning director Alex Gibney's latest biographical documentary—simply titled Musk—covers a lot of well-known ground and challenges the carefully crafted public image of Musk as a visionary tech titan.

Gibney's documentary presents Musk as more of a Gilded Age confidence man, rejiggered for the 21st century: an investor cosplaying as an inventor whose real genius is pumping stocks and dazzling investors and the public alike with visions of a high-tech utopian future. The film is bound to push all the right outrage buttons, whether one is a Musk fan or a detractor—which makes it very much a product of the peculiar social media-driven era in which we live.

Gibney has been making documentaries since the 1980s, covering such varied subjects as Jimi Hendrix, Hunter S. Thompson and gonzo journalism, WikiLeaks, Scientology, Steve Jobs, Elizabeth Holmes (the subject of another forthcoming documentary, You Can See Everything, featuring comedian Nathan Fielder), Boris Becker, The Sopranos creator David Chase, alleged Russian interference in the US 2016 presidential election, the opioid epidemic, and cyclist Lance Armstrong. He snagged his first Oscar nomination for 2005’s Enron: The Smartest Guys in the Room, and won the Oscar for Best Documentary Feature two years later for Taxi to the Dark Side.
