AWS is making several availability changes to various services and features across three categories. Some services are moving to maintenance, meaning no new customers can access them after November 7, 2025, but existing users can continue utilizing them. A list of these services includes Amazon Cloud Directory, CodeCatalyst, and others, totaling 17 services. Certain services are entering a sunset phase, with sunset dates announced, requiring customers to migrate within approximately a year. These include Amazon FinSpace, Lookout for Equipment, and two other services. AWS Mainframe Modernization App Testing has already reached its end-of-support date, rendering it unavailable from October 7, 2025. Users of sunset services should consult the provided links for migration timelines and guidance. These changes impact customers who are using these services and features. AWS offers migration guides and support to assist affected customers in transitioning. Customers are encouraged to visit the AWS Product Lifecycle Page for comprehensive information. AWS support is ready to assist.
