A widespread Amazon Web Services (AWS) outage caused significant disruptions to numerous websites, applications, and services, including popular platforms like Venmo, Snapchat, and Canva. The issue stemmed from a DNS resolution problem with the DynamoDB API in the US-EAST-1 region, impacting services across various AWS components such as EC2. While AWS mitigated the initial DNS issue, knock-on effects continued to cause problems, particularly with new EC2 instance launches, prompting recommendations for users.
On this crisp October morning, it feels like half of the internet is dealing with a hangover. A severe Amazon Web Services outage took out many, many websites, apps, games and other services that rely on Amazon’s cloud division to stay up and running.
That includes a long list of popular software like Venmo, Snapchat, Canva and. Even Amazon's own assistant Alexa has been stuttering, and if you're wondering why the internet seems to be against you today — you're not imagining it., Amazon was looking into "increased error rates and latencies for multiple AWS services" in the US-EAST-1 region as of 3:11AM ET on Monday. By 5:01AM, AWS had figured out that a DNS resolution issue with its DynamoDB API was the cause of the outage. DynamoDB is a database that holds info for AWS clients. “Amazon had the data safely stored, but nobody else could find it for several hours, leaving apps temporarily separated from their data,” Mike Chapple, a teaching professor of IT, analytics and operations at University of Notre Dame, toldAs of 6:35AM, AWS said it had fully mitigated the DNS issue and that "most AWS Service operations are succeeding normally now." However, the knock-on effect caused issues with other AWS services, including EC2, a virtual machine service on which many companies build online applications. At 8:48AM, AWS said it was "making progress on resolving the issue with new EC2 instance launches in the US-EAST-1 Region." It recommended that clients not tie new deployments to specific Availability Zones "so that EC2 has flexibility" in picking a zone that may be a better option. At 9:42AM, Amazon noted on the status page that although it had applied "multiple mitigations" across several Availability Zones in US-EAST-1, it was "still experiencing elevated errors for new EC2 instance launches." As such, AWS was "rate limiting new instance launches to aid recovery." The company added at 10:14AM that it was seeing "significant API errors and connectivity issues across multiple services in the US-EAST-1 Region." Even once all the issues are resolved, AWS will have a significant backlog of requests and other factors to process, so it'll take some time for everything to recover. Many, many, many companies use US-EAST-1 for their AWS deployments, which is why it felt like half of the internet was knocked offline on Monday morning. As of mid-morning, tons of websites and other services were sluggish or offering up error messages. Outage reports for a broad swathe of services spiked on Down Detector. Along with Amazon's own services, users reported issues with the likes of banks, airlines, Disney+, Snapchat, Reddit, Lyft, Apple Music, Pinterest,, and though they don't explicitly mention AWS, it's possible that the services' paths may cross somewhere in the pipelines. AWS offers a lot of useful features to clients, such as the ability for websites and apps to automatically scale compute and server capacity up and down as needed to handle ebbs and flows in traffic. It also has data centers around the world. That kind of infrastructure is attractive to companies that serve a global audience and need to stay online around the clock. As of mid-2025, it wasthat AWS' share of the worldwide cloud infrastructure market was 30 percent. But incidents such as this highlight that relying on just a few providers to be the backbone of much of the internet is a bit of a problem.- A twice-weekly dose of the news you need
