ReutersAWS outage: Amazon reveals root cause as cloud services ‘returned to normal operations. In a massive relief, Amazon said on Monday evening (October 20, 2025) that a massive outage of its cloud computing service has been resolved after a problem disrupted internet use around the world. The disruption took down a massive range of online services, including social media, gaming, food delivery, streaming, and financial platforms.The root cause that triggered the massive outage was a malfunction at Amazon Web Services (AWS), the tech giant's cloud computing division. AWS provides behind-the-scenes cloud computing infrastructure to some of the world’s biggest organizations. Its customers include government departments, universities, and businesses. “By 3:01 PM, all AWS services returned to normal operations. Some services such as AWS Config, Redshift, and Connect continue to have a backlog of messages that they will finish processing over the next few hours. We will share a detailed AWS post-event summary,” according to AWS Health Dashboard.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.Amazon blames the domain name systemThe retail giant 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.Live EventsIn an update on its status page, AWS said that there are "increased error rates and latencies for multiple AWS Services in the US-EAST-1 Region." Engineers are "immediately engaged and are actively working on both mitigating the issue, and fully understanding the root cause", it adds.DownDetector says over 11 million users reported problems at more than 2,500 companies 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.Among those affected were Amazon's own services. 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.According to AP, 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.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.Add as a Reliable and Trusted News Source Add Now!
