A cellular outage early on Thursday hit thousands of AT&T users in the United States, disrupting calls and text messages as well as emergency services in major cities including San Francisco.

About 58,000 incidents were reported around noon ET, according to data from outage-tracking website Downdetector.com. AT&T has not said exactly how many customers were affected by Thursday’s outage and the cause was not immediately clear.

“Some of our customers are experiencing wireless service interruptions this morning,” AT&T said Thursday on a site it put up for updates to the situation. “Our network teams took immediate action and so far three-quarters of our network has been restored. We are working as quickly as possible to restore service to remaining customers.”

Phones affected by the outage have displayed zero service bars in the top right corner of their device or the letters SOS. Customers were still able to make calls by enabling Wi-Fi calling.

A spike in outages began around 4:00 a.m. ET and peaked at around 74,000 reported incidents at 8:30 a.m. ET, according to Downdetector.

Shares of AT&T were down about 2% Thursday morning following the outages.

The AT&T outage has impacted people’s ability to reach emergency services by dialing 911, a post on social media platform X from the San Francisco Fire Department said.

“We are aware of an issue impacting AT&T wireless customers from making and receiving any phone calls (including to 911),” the fire department said on the platform.

Atlanta Mayor Andre Dickens said in a post on X that the city can receive and make outbound 911 calls but that AT&T customers in the area had reported issues.

“We have received calls from AT&T customers that their cellular phones are in SOS mode. Please direct all inquiries to restore service to AT&T,” Dickens said.

The Massachusetts State Police said that people were flooding their 911 center with calls trying to determine if the service works from their cell phones.

“Please do not do this. If you can successfully place a non-emergency call to another number via your cell service then your 911 service will also work,” the state police said in a post on X.

Users of Verizon and T-Mobile were reporting a few thousand outages each as of 10:00 a.m. ET, according to Downdetector.

These reports were likely due to calls made trying to connect with other networks, both companies said.

“Downdetector is likely reflecting challenges our customers were having attempting to connect to users on other networks,” T-Mobile said in an emailed statement.

How quantum could supercharge Google’s AI ambitions

Inside a secretive set of buildings in Santa Barbara, California, scientists at Alphabet are working on one of the company’s most ambitious bets yet. They’re attempting to develop the world’s most advanced quantum computers.

“In the future, quantum and AI, they could really complement each other back and forth,” said Julian Kelly, director of hardware at Google Quantum AI.

Google has been viewed by many as late to the generative AI boom, because OpenAI broke into the mainstream first with ChatGPT in late 2022.

Late last year, Google made clear that it wouldn’t be caught on the backfoot again. The company unveiled a breakthrough quantum computing chip called Willow, which it says can solve a benchmark problem unimaginably faster than what’s possible with a classical computer, and demonstrated that adding more quantum bits to the chip reduced errors exponentially. 

“That’s a milestone for the field,” said John Preskill, director of the Caltech Institute for Quantum Information and Matter. “We’ve been wanting to see that for quite a while.”

Willow may now give Google a chance to take the lead in the next technological era. It also could be a way to turn research into a commercial opportunity, especially as AI hits a data wall. Leading AI models are running out of high-quality data to train on after already scraping much of the data on the internet.

“One of the potential applications that you can think of for a quantum computer is generating new and novel data,” said Kelly. 

He uses the example of AlphaFold, an AI model developed by Google DeepMind that helps scientists study protein structures. Its creators won the 2024 Nobel Prize in Chemistry. 

“[AlphaFold] trains on data that’s informed by quantum mechanics, but that’s actually not that common,” said Kelly. “So a thing that a quantum computer could do is generate data that AI could then be trained on in order to give it a little more information about how quantum mechanics works.” 

Kelly has said that he believes Google is only about five years away from a breakout, practical application that can only be solved on a quantum computer. But for Google to win the next big platform shift, it would have to turn a breakthrough into a business.

Nintendo Switch 2 retail preorder to begin April 24 following tariff delays

Nintendo on Friday announced that retail preorder for its Nintendo Switch 2 gaming system will begin on April 24 starting at $449.99.

Preorders for the hotly anticipated console were initially slated for April 9, but Nintendo delayed the date to assess the impact of the far-reaching, aggressive “reciprocal” tariffs that President Donald Trump announced earlier this month.

Most electronics companies, including Nintendo, manufacture their products in Asia. Nintendo’s Switch 1 consoles were made in China and Vietnam, Reuters reported in 2019. Trump has imposed a 145% tariff rate on China and a 10% rate on Vietnam. The latter is down from 46%, after he instituted a 90-day pause to allow for negotiations.

Nintendo said Friday that the Switch 2 will cost $449.99 in the U.S., which is the same price the company first announced on April 2.

“We apologize for the retail pre-order delay, and hope this reduces some of the uncertainty our consumers may be experiencing,” Nintendo said in a statement. “We thank our customers for their patience, and we share their excitement to experience Nintendo Switch 2 starting June 5, 2025.”

The Nintendo Switch 2 and “Mario Kart World bundle will cost $499.99, the digital version “Mario Kart World” will cost $79.99 and the digital version of “Donkey Kong Bananza” will cost $69.99, Nintendo said. All of those prices remain unchanged from the company’s initial announcement.

However, accessories for the Nintendo Switch 2 will “experience price adjustments,” the company said, and other future changes in costs are possible for “any Nintendo product.”

It will cost gamers $10 more to by the dock set, $1 more to buy the controller strap and $5 more to buy most other accessories, for instance.

Etsy touts 'shopping domestically' as Trump tariffs threaten price increases for imports

Etsy is trying to make it easier for shoppers to purchase products from local merchants and avoid the extra cost of imports as President Donald Trump’s sweeping tariffs raise concerns about soaring prices.

In a post to Etsy’s website on Thursday, CEO Josh Silverman said the company is “surfacing new ways for buyers to discover businesses in their countries” via shopping pages and by featuring local sellers on its website and app.

“While we continue to nurture and enable cross-border trade on Etsy, we understand that people are increasingly interested in shopping domestically,” Silverman said.

Etsy operates an online marketplace that connects buyers and sellers with mostly artisanal and handcrafted goods. The site, which had 5.6 million active sellers as of the end of December, competes with e-commerce juggernaut Amazon, as well as newer entrants that have ties to China like Temu, Shein and TikTok Shop.

By highlighting local sellers, Etsy could relieve some shoppers from having to pay higher prices induced by President Trump’s widespread tariffs on trade partners. Trump has imposed tariffs on most foreign countries, with China facing a rate of 145%, and other nations facing 10% rates after he instituted a 90-day pause to allow for negotiations. Trump also signed an executive order that will end the de minimis provision, a loophole for low-value shipments often used by online businesses, on May 2.

Temu and Shein have already announced they plan to raise prices late next week in response to the tariffs. Sellers on Amazon’s third-party marketplace, many of whom source their products from China, have said they’re considering raising prices.

Silverman said Etsy has provided guidance for its sellers to help them “run their businesses with as little disruption as possible” in the wake of tariffs and changes to the de minimis exemption.

Before Trump’s “Liberation Day” tariffs took effect, Silverman said on the company’s fourth-quarter earnings call in late February that he expects Etsy to benefit from the tariffs and de minimis restrictions because it “has much less dependence on products coming in from China.”

“We’re doing whatever work we can do to anticipate and prepare for come what may,” Silverman said at the time. “In general, though, I think Etsy will be more resilient than many of our competitors in these situations.”

Still, American shoppers may face higher prices on Etsy as U.S. businesses that source their products or components from China pass some of those costs on to consumers.

Etsy shares are down 17% this year, slightly more than the Nasdaq.
