A high-profile Google developer has proposed that the Internet Engineering Task Force (IETF) that it endorse a new HTTP Status Code to warn readers the page they're looking for has been censored by authorities,
according to TheVerge.
Tim Bray, who co-invented XML and works as Android Developer Advocate at Google, is submitting a proposal that pages censored by someone other than the owner of the site or of the user's local network display the error code "451 Unavailable for Legal Reasons."
