We all know John Gilmore’s famous dictum: “The Net interprets censorship as damage and routes around it.”
True, but with governments doing what they do (and with more bandwidth being centralized in the hands of fewer, larger ISPs), routing around damage isn’t necessarily an automatic thing.
From C^2 comes word of a new book (available free in HTML, pdf, and epub, available for purchase in dead tree format): How to Bypass Internet Censorship. Forgive it for opening with the U.N. Declaration of Human Rights; to some people in the world, that’s an improvement over what they’ve got locally. I haven’t read the whole thing, but it looks like a pretty good guide, C^2 says it’s backed and partly funded by the good people of the Electronic Frontier Foundation, and it’s free.
Tell your friends in less free places. Snag a copy for your own reference, come the day. (Even short of that day, it appears to contain a good explanation of how censorship works, how to circumvent it, and what risks are involved.)
