The Document Which Used to Be Called the MIT Lockpicking Guide (1992)
This link is censored in the U.K.<p>EE says something about it being locked, while Three sends you to a page with 503 in the URL, and this text:<p><pre><code>    Oops!
    Sorry, there is a slight technical glitch.
    Please reboot your device to reconnect to the services.
    Sorry for the inconvenience.
</code></pre>
Other sites like torproject.org are behind the porn filter which require you to go to a store with ID to lift it.<p>I don't know why I still let my connections exit in the U.K., or live here really.
