New HTTP Error Code Approved: 451. Sites Blocked For Illegal Content.
The new protocol, named after Ray Bradbury's novel Fahrenheit 451, was approved by the Internet Engineering Steering Group (IESG).
“Unavailable For Legal Reasons”
Text of HTTP error 451
"This status code can be used to provide transparency in circumstances where issues of law or public policy affect server operations," the newly published code states. "This transparency may be beneficial both to these operators and to end users."
The 451 status code has been approved for publication and can "effectively" be put to use immediately, according to chair of the IETF HTTP Working Group Mark Nottingham, however the Request for Comments (RFC) Editor is still working on the protocol.
