> SOLR-12999 introduced a new behavior where Solr nodes can now know to quickly reject requests when the index is unavailable due to a full IndexFetch from the master/leader - but when this change was implemented it was done soe using the HTTP status code "403" (Forbidden) which semantically indicates a _client_ error and carries with it the understanding that the client should not re-attempt the request ... at least not w/o modification (typically adding authentication information)
> A more semantically correct response code would be 503 (Service Unavailable) which indicates a _server_ problem (that may be resolved at some point in the future) and clients would not be ill-behaved to try again later.
> returning 503 in this particular code path would also be more consistent with other places in the solr code based where nodes respond with "503" when they are "not _currently_ ready for requests" (but might be soon)
