Amazon reported a major outage in the us-east-1 (Northern Virginia) region after a race condition in DynamoDB's DNS management created an empty DNS record for the regional endpoint, which removed IP addresses and caused cascading DNS failures across AWS services; automated recovery could not fix the inconsistent state, requiring manual intervention and prompting Amazon to disable the faulty automation and add protective checks and tests.
