AWS Fixes US-East-1 DNS Outage Vulnerability
30 Nov
Summary
- AWS introduced a new feature for 60-minute DNS recovery in US-East-1.
- The update targets mission-critical applications in banking and FinTech.
- This feature requires manual activation by users in the AWS console.
Amazon Web Services is enhancing its US-East-1 region's resilience following a significant outage in October 2025. The cloud provider has introduced a new business-continuity feature for Amazon Route 53, promising a 60-minute recovery time objective for Domain Name System (DNS) disruptions. This crucial update aims to ensure customers can continue managing DNS and provisioning infrastructure even during outages.
The new feature is particularly designed to benefit mission-critical applications in industries such as banking, FinTech, and Software as a Service (SaaS). It will enable users to rapidly provision standby cloud resources or reroute traffic when necessary, mitigating the impact of unexpected service interruptions.
However, this enhanced stability measure is not enabled by default. AWS Route 53 users must manually activate "Accelerated Recovery" through the AWS Management Console's Hosted Zones section. This proactive step addresses ongoing concerns about the operational stability of the US-East-1 region, known for its high traffic density and past outage proneness.
