Affected Services and Companies by the AWS DNS Outage on October 20, 2025

Posted by Zack Hamm on October 22, 2025

So, apart from bean counters constantly purporting that corporations are saving money in the cloud, the general premise is that the cloud is more “resilient” than your own corporate data center, and by offloading that infrastructure to the cloud you are more robust, resilient, and secure. Then… AWS has a major outage and proves all of this wrong.

On October 20, 2025, a DNS resolution failure in AWS’s US-EAST-1 region (Northern Virginia) caused widespread disruptions, primarily affecting DynamoDB and cascading to other services like EC2, Lambda, and SQS. The outage began around 3:11 AM ET (12:11 AM PDT) and the core DNS issue was fully mitigated by approximately 6:35 AM ET (3:35 AM PDT), lasting about 3-4 hours at its peak. However, full recovery for many dependent services took longer due to backlogs and cached DNS issues, with some disruptions extending up to 7-15 hours or into the afternoon ET. AWS advised flushing DNS caches to speed recovery, and all services were reported back to normal by around 6:53 PM ET.

Below is a comprehensive list of affected companies and services, aggregated from reports. Downtime estimates are approximate based on user reports and official updates, as exact durations varied by region and service. Services are categorized for clarity.

This list covers over 100 reported services, though not all may have been equally impacted globally. The outage highlighted dependencies on AWS, affecting millions and costing businesses potentially billions in lost productivity. No cyberattack was involved; it was an internal technical fault.
