Gary Illyes from Google came on to Twitter for a brief moment to share a PSA about 429/503 HTTP status codes. He said while you probably know 429/503 HTTP status codes will slow GoogleBot's crawling activity, what you might not know is that if those codes are left in place for too long, it can remove the pages completely from the Google index.
