Summary

Hide ▲

An ongoing AWS outage in the US-EAST-1 region has caused widespread disruption to multiple services, including Amazon.com, Prime Video, Perplexity AI, Canva, Fortnite, and others. The outage, which began on October 19, affected users in various regions, including the United States and Europe, for over two days. AWS has acknowledged the issue and is working to mitigate it and identify the root cause. The outage is causing increased error rates and latencies for multiple AWS services, impacting both end-users and support operations. The outage was caused by a major DNS failure in the DynamoDB infrastructure, specifically a race condition that led to the accidental deletion of all IP addresses for the database service's regional endpoint. AWS has taken measures to prevent similar issues in the future, including disabling the buggy DNS automation globally and adding protective checks and improved throttling mechanisms. The outage highlighted the risks of relying on a single cloud provider and the need for resilient security strategies. AI-powered platforms like Wild Moose can help with rapid root cause analysis during outages, aiding in incident response.
