Evidence boundary: Workers KV continues. The retired surface is the legacy namespace route family.
What changes
Requests using /workers/namespaces/* must move to /storage/kv/namespaces/*. Existing automation that retains the old path will stop working after the deadline.
Who is affected
- Direct API clients using the legacy namespace path.
- Internal tools with hard-coded Workers KV URLs.
- Libraries or scripts that have not adopted the newer storage route.
Timeline
The legacy routes retire on 15 October 2026.
Required action
- Search code, runbooks and CI jobs for the old route prefix.
- Replace it with the supported storage-path equivalent.
- Retest namespace creation, listing, deletion and related operations.
What is not affected
Workers KV itself remains available. This record does not imply a retirement of KV storage or every Workers API.
PlatformTrace analysis
The change is syntactically narrow but operationally hard: callers that do not change the route will receive failed requests after retirement.
