We haven't faced any outages or issues directly related to Route 53. It has been 100% stable for me.
Amazon Route 53 is valued for scalability and easy setup. It efficiently manages DNS with health check features and integrates seamlessly with AWS services. While it offers cost-effective domain management, areas like concurrent request handling, pricing transparency, and integration with on-premise infrastructure need improvement. Security features should be enhanced, and high usage may lead to increased costs. These advancements could boost service stability and reliability.
