An Amazon AWS outage impacted several users on 20 October 2025 causing widespread outage. Several services went down for hours due to a DNS resolution failure that disrupted DynamoDB, a critical AWS database service storing vast amounts of data. Due to this technical error, services such as IAM and DynamoDB Global Tables, which are dependent on the US-EAST-1 endpoints, could not identify or locate the DynamoDB that in turn led to significant downtime and delays. Although Amazon Web Services restored the issue impacting the DynamoDB DNS thus resolving initial access to the service.

In addition to these issues, AWS Network Load Balancer health checks failed, breaking network connectivity for services like Lambda, CloudWatch, SQS, and 75+ other services. All of this led to a domino effect wherein servers could not communicate creating several backlogs as requests had already piled up and new instances could not get started.
