Amazon Web Services (AWS) confirmed that a widespread internet outage occurring on Monday was triggered by a critical DNS resolution failure. The disruption impacted a significant portion of the web, rendering numerous websites, banking platforms, and government services inaccessible for hours. By 6:01 p.m. ET, Amazon officially announced that all AWS services had returned to normal operations.
The Root Cause: A DNS Resolution Breakdown
In an official announcement, Amazon identified the technical catalyst behind the blackout. The issue stemmed from the Domain Name System (DNS)—the infrastructure responsible for translating web addresses into IP addresses. Specifically, the company reported increased error rates linked to DNS resolution for DynamoDB API endpoints within the N. Virginia (us-east-1) region. The underlying issue was successfully mitigated at 2:24 AM PDT.
Widespread Impact Across Global Apps
The outage caused massive instability for millions of users, affecting both Amazon’s internal operations and major third-party platforms. High-profile services that faced significant downtime included:
Amazon’s own services, such as Ring surveillance products, were also crippled. The disruption even reached smart home hardware, with reports of Eight Sleep cooling pods failing, disturbing users’ sleep cycles.
The Fragility of Cloud Infrastructure
AWS holds an estimated 30% of the global cloud market, hosting essential systems for organizations worldwide. This incident highlights the concentration of internet traffic within a few major data center hubs.
This event follows a history of large-scale digital failures. In 2024, a faulty update from cybersecurity firm CrowdStrike caused global system crashes, impacting airports and critical infrastructure. Similarly, a 2021 malfunction at DNS provider Akamai caused major platforms like PlayStation Network, Steam, and FedEx to drop off the web for several hours.
Recovery and Monitoring
While the immediate technical glitch was resolved, Amazon continued to work through the evening to ensure full restoration across all customer support operations. The company directed users to the AWS Health Dashboard for ongoing updates and detailed status reporting.
