I'm sure I've seen 410 in the wild, but it's pretty uncommon. If you're keeping track of things well enough to know that there used to be a page there in order to serve a 410, you're probably keeping track of things well enough to be able to do something better, like redirect to an updated URL. > Who knew there were so many different status codes. As an HTTP nerd, the authoritative listing of the different codes is: https://www.iana.org/assignments/http-status-codes https://www.iana.org/assignments/http-status-codes Note: Everything with a reference that's not RFC 7231 is an extension; don't use that status code unless you actually implement that extension. For example, don't use 401 (Unauthorized) instead of 403 (Forbidden) unless you actually implement the RFC 7235 Authentication extension.
