On October 20, 2025, Amazon Web Services (AWS) experienced a major outage starting around 3 a.m. ET that disrupted a huge portion of the internet. The root cause was a DNS issue within AWS’s DynamoDB database service in its largest data center region—us-east-1 in Northern Virginia. This DNS failure meant that many apps and websites could not resolve the addresses of critical servers, causing widespread failures and outages in popular services such as Snapchat, Ring, Alexa, Fortnite, and various banking, gaming, and smart home platforms. The disruption lasted several hours, with primary problems resolved by around 6 a.m. ET and full recovery of all services by late evening. The outage revealed how heavily modern digital services depend on AWS’s cloud infrastructure, and it affected 113 AWS services in total, causing a global ripple effect including delays, timeouts, and loss of functionality across many sectors.

In summary, what happened at AWS was a key DNS failure tied to DynamoDB, rendering many online platforms temporarily unreachable and underscoring the fragility of internet infrastructure when reliant on a few dominant cloud providers.
