We haven't faced any outages or issues directly related to Route 53. It has been 100% stable for me.
Amazon Route 53 effectively monitors resource health and manages DNS with capabilities like failover and geolocation routing. It integrates seamlessly with AWS services such as S3, EC2, and Lambda. While fast and scalable, it faces challenges in on-premise integration and management workflow automation. Pricing transparency and security features need improvement, and support lacks communication options like chat support.
