Error 451: A proposed Internet status code for censorship

If a website you're trying to reach is blocked for legal reasons, do you have a right to know about it? Developer advocate Tim Bray thinks so, and he's got a perfect error code for it: 451, a tribute to the late Ray Bradbury's landmark novel about censorship, Fahrenheit 451.

Bray, a self-described "general-purpose Web geek" who helped develop several key Internet standards, wrote a formal specification for his proposal and submitted it to the Internet Engineering Task Force (IETF), the body that develops and promotes Internet standards. The group is slated to take up Bray's proposal at next week's annual meeting, which begins July 29 in Vancouver, Canada.
