AWS outage: DynamoDB DNS failure caused disruption

⚠️ Amazon says a major DNS failure in DynamoDB's DNS management system triggered a widespread AWS outage focused on the us-east-1 (Northern Virginia) region. A race condition at 11:48 PM PDT caused the accidental deletion of all IP addresses for the regional DynamoDB public endpoint, producing immediate DNS resolution failures for customer and internal traffic. The fault cascaded across services, kept automated recovery from restoring consistency, and required manual operator intervention to recover. AWS has disabled the problematic DNS automation globally, added protective checks, improved throttling, built new test suites, and apologized for the impact.
