💨 Abstract

On Monday, an AWS outage affected thousands of websites and apps globally due to a software bug in DynamoDB's DNS management system. The issue, which lasted several hours, impacted over 2,000 services across more than 60 countries, including government sites, banks, games, streaming services, airlines, and crypto platforms. The outage was caused by a latent defect during an update, leading to DNS failures. While many services recovered quickly, others took hours to restore.
