The 451 status code is now supported
I actually saw the status code 451 in the wild.<p>First time I saw it was in December and after that in January, both on the same site. The site that was blocked was archive.is.<p>This block was targeted at Finland and none of the different Internet connections I tried could get to the site, I tried my home connection, cellular and connecting from my school network. It's a shame that anyone even thought of censoring such an useful tool for history and other legitimate uses. I wrote a thing about it to a Finnish newspaper and a few weeks after that the block was gone. I suspect that the newspaper conatcted archive.is and it was removed so they don't get bad publicity.<p>It was kind of ironical that I had to subvert the archive.is censorship to read an archived version of a thread discussing web censorship in Sweden.<p>I think this error code is a bad idea as it legitimizes censorship.
