+## [Unreleased]
+
+### Fixed
+
+- Deleting a redirect from the admin redirects list (`IRedirectsService.DeleteById`) now raises `RedirectsEvents.RedirectsUpdated`, like every other write on `DefaultRedirectsService`. Before, the deleted redirect kept applying until the application restarted or another redirect was saved, and `OptimizelySyncEvents` never told the other instances.
+
 ## [6.1.0]
 
 ### Added
