Massive Amazon cloud outage has been resolved after disrupting internet use worldwide

LONDON (AP) — Amazon says a massive outage of its cloud computing service has been resolved as of Monday evening, after a problem disrupted internet use around the world, taking down a broad range of online services, including social media, gaming, food delivery, streaming and financial platforms.

The all-day disruption and the ensuing exasperation it caused served as the latest reminder that 21st century society is increasingly dependent on just a handful of companies for much of its internet technology, which seems to work reliably until it suddenly breaks down.

About three hours after the outage began early Monday morning, Amazon Web Services said it was starting to recover, but it wasn't until 6 p.m. Eastern that “services returned to normal operations,” Amazon said on its AWS health website, where it tracks outages.

AWS provides behind-the-scenes cloud computing infrastructure to some of the world’s biggest organizations. Its customers include government departments, universities and businesses, including The Associated Press.

Cybersecurity expert Mike Chapple said “a slow and bumpy recovery process” is “entirely normal.”

As engineers roll out fixes across the cloud computing infrastructure, the process could trigger smaller disruptions, he said.

“It’s similar to what happens after a large-scale power outage: While a city’s power is coming back online, neighborhoods may see intermittent glitches as crews finish the repairs,” said Chapple, an information technology professor at the University of Notre Dame’s Mendoza College of Business.

Amazon pinned the outage on issues related to its domain name system that converts web addresses into IP addresses, which are numeric designations that identify locations on the internet. Those addresses allow websites and apps to load on internet-connected devices.

DownDetector, a website that tracks online outages, said in a Facebook post that it received over 11 million user reports of problems at more than 2,500 companies. Users reported trouble with the social media site Snapchat, the Roblox and Fortnite video games, the online broker Robinhood and the McDonald’s app, as well as Netflix, Disney+ and many other services.

The cryptocurrency exchange Coinbase and the Signal chat app both said on X that they were experiencing trouble related to the outage.

Amazon's own services were also affected. Users of the company's Ring doorbell cameras and Alexa-powered smart speakers reported that they were not working, while others said they were unable to access the Amazon website or download books to their Kindle.

Many college and K-12 students were unable to submit or access their homework or course materials Monday because the AWS outage knocked out Canvas, a widely used educational platform.

“I currently can’t grade any online assignments, and my students can’t access their online materials” because of the outage’s effect on learning-management systems, said Damien P. Williams, a professor of philosophy and data science at the University of North Carolina at Charlotte.

The exact number of schools impacted was not immediately known, but Canvas says on its website it is used by 50% of college and university students in North America, including all Ivy League schools in the U.S.

At the University of California, Riverside, students couldn’t submit assignments, take quizzes or access course materials, and online instruction was limited, the campus said.

Ohio State University informed its 70,000 students at all six campuses by email Monday morning that online course materials might be inaccessible due to the outage and that “students should connect with their instructors for any alternative plans.” As of 7:10 p.m. Eastern, access was restored, the university told students.

This is not the first time issues with Amazon cloud services have caused widespread disruptions.

Many popular internet services were affected by a brief outage in 2023. AWS’s longest outage in recent history occurred in late 2021, when a wide range of companies — from airlines and auto dealerships to payment apps and video streaming services — were affected for more than five hours. Outages also happened in 2020 and 2017.

The first signs of trouble emerged at around 3:11 a.m. Eastern time, when AWS reported on its “health dashboard” that it was “investigating increased error rates and latencies for multiple AWS services in the US-EAST-1 Region.” Later, the company reported that there were “significant error rates” and that engineers were “actively working” on the problem.

Around 6 a.m. Eastern time, the company reported seeing recovery across most of the affected services and said it was seeking a “full resolution." As of midday, AWS was still working to resolve the trouble.

Sixty-four internal AWS services were affected, the company said.

Because much of the world now relies on three or four companies to provide the underlying infrastructure of the internet, “when there’s an issue like this, it can be really impactful” across many online services, said Patrick Burgess, a cybersecurity expert at U.K.-based BCS, The Chartered Institute for IT.

“The world now runs on the cloud,” Burgess said.

And because so much of the online world’s plumbing is underpinned by so few companies, when something goes wrong, “it’s very difficult for users to pinpoint what is happening because we don’t see Amazon, we just see Snapchat or Roblox,” Burgess said.

“The good news is that this kind of issue is usually relatively fast" to resolve, and there’s no indication that it was caused by a cyberattack, Burgess said.

“This looks like a good old-fashioned technology issue. Something’s gone wrong, and it will be fixed by Amazon,” he said.

There are “well-established processes” to deal with outages at AWS, as well as rivals Google and Microsoft, Burgess said, adding that such outages are usually over in “hours rather than days.”

U.S. President Donald Trump says Iran has proposed negotiations after his threat to strike the Islamic Republic as an ongoing crackdown on demonstrators has led to hundreds of deaths.

Trump said late Sunday that his administration was in talks to set up a meeting with Tehran, but cautioned that he may have to act first as reports mount of increasing deaths and the government continues to arrest protesters.

“The meeting is being set up, but we may have to act because of what’s happening before the meeting. But a meeting is being set up. Iran called, they want to negotiate,” Trump told reporters on Air Force One on Sunday night.

Iran did not acknowledge Trump’s comments immediately. It has previously warned the U.S. military and Israel would be “legitimate targets” if America uses force to protect demonstrators.

The U.S.-based Human Rights Activists News Agency, which has accurately reported on past unrest in Iran, gave the death toll. It relies on supporters in Iran crosschecking information. It said at least 544 people have been killed so far, including 496 protesters and 48 people from the security forces. It said more than 10,600 people also have been detained over the two weeks of protests.

With the internet down in Iran and phone lines cut off, gauging the demonstrations from abroad has grown more difficult. Iran’s government has not offered overall casualty figures.

The Latest:

The semiofficial Fars news agency in Iran, which is close to the paramilitary Revolutionary Guard, on Monday began calling out Iranian celebrities and leaders on social media who have expressed support for the protests over the past two weeks, especially before the internet was shut down.

The threat comes as writers and other cultural leaders were targeted even before protests. The news agency highlighted specific celebrities who posted in solidarity with the protesters and scolded them for not condemning vandalism and destruction to public property or the deaths of security forces killed during clashes. The news agency accused those celebrities and leaders of inciting riots by expressing their support.

Canada said it “stands with the brave people of Iran” in a statement on social media that strongly condemned the killing of protesters during widespread protests that have rocked the country over the past two weeks.

“The Iranian regime must halt its horrific repression and intimidation and respect the human rights of its citizens,” Canada’s government said on Monday.

Iran’s foreign minister claimed Monday that “the situation has come under total control” after a bloody crackdown on nationwide protests in the country.

Abbas Araghchi offered no evidence for his claim.

Araghchi spoke to foreign diplomats in Tehran. The Qatar-funded Al Jazeera satellite news network, which has been allowed to work despite the internet being cut off in the country, carried his remarks.

Iran’s foreign minister alleged Monday that nationwide protests in his nation “turned violent and bloody to give an excuse” for U.S. President Donald Trump to intervene.

Abbas Araghchi offered no evidence for his claim, which comes after over 500 have been reported killed by activists -- the vast majority coming from demonstrators.

Iran has summoned the British ambassador over protesters twice taking down the Iranian flag at their embassy in London.

Iranian state television also said Monday that it complained about “certain terrorist organization that, under the guise of media, spread lies and promote violence and terrorism.” The United Kingdom is home to offices of the BBC’s Persian service and Iran International, both which long have been targeted by Iran.

A huge crowd of demonstrators, some waving the flag of Iran, gathered Sunday afternoon along Veteran Avenue in LA’s Westwood neighborhood to protest against the Iranian government. Police eventually issued a dispersal order, and by early evening only about a hundred protesters were still in the area, ABC7 reported.

Los Angeles is home to the largest Iranian community outside of Iran.

Los Angeles police responded Sunday after somebody drove a U-Haul box truck down a street crowded with the the demonstrators, causing protesters to scramble out of the way and then run after the speeding vehicle to try to attack the driver. A police statement said one person was hit by the truck but nobody was seriously hurt.

The driver, a man who was not identified, was detained “pending further investigation,” police said in a statement Sunday evening.
