The 451 status code is now supported
I actually saw the status code 451 in the wild.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.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removed so they don't get bad publicity.It was kind of ironical that I had to subvert the archive.is censorship to read an archived version of a thread discussing web censorship in Sweden.I think this error code is a bad idea as it legitimizes censorship.
