AWS told customers that several services will change status. Starting Oct 29, 2026, the Amazon Chime SDK SIP Media Application and Amazon WorkSpaces Secure Browser will go into maintenance mode, meaning new users can’t sign up. Three services – Amazon Managed Blockchain, Amazon DevOps Guru and AWS Backint Agent for SAP ASE – are slated to sunset by Sep 29‑30, 2027, with a console‑only end for AWS Infrastructure Composer on Dec 7, 2026. Amazon Mechanical Turk has already reached end of support as of Sep 29, 2026.

## The facts

- Mechanical Turk stopped being available on Sep 29, 2026
- Managed Blockchain support ends Sep 29, 2027

## Why it matters

Customers must plan migrations now to avoid service interruptions.
