We haven't faced any outages or issues directly related to Route 53. It has been 100% stable for me.
Amazon Route 53 offers highly scalable DNS management and traffic routing, with straightforward setup and fast DNS resolution. Seamlessly integrating with AWS services like S3, EC2, and Lambda, it ensures effective resource health monitoring. Despite offering robust security and customer support, improvements in handling simultaneous requests, on-premise integration, detailed logging, and pricing optimization are necessary. Enhancements in DNSSEC and disaster recovery features are also needed for advanced scenarios.
