HTTP 410 status code means a resource (e.g., document or file) is gone forever.
410 Gone implies that the resource was intentionally removed, and clients shouldn’t look for it in the future. Think of it as a more specific version of
404 Not Found, which doesn’t imply anything about the future availability of the resource.
When in doubt, use 404.
Search engines remove the page from their indices upon encountering the
410 Gone status code.
