we are now treating 410s slightly differently than 404s. In particular, as I mentioned above, when we see a 404 we’ll sometimes want to confirm it to make sure that it’s a permanent removal. With a 410 HTTP result code, we don’t need to do that. In practice, for most sites, the difference will be minimal. When a URL returns 410, we might still crawl it from time to time though, just to make sure that it’s still returning a 404\/410. If you can’t serve a 410 HTTP result code, then that’s fine — this is not critical. <\/p><\/blockquote>\n
