Most schools and corporations are protected from visiting outside websites to help reduce spam and intruder attacks. This guide will show you how to access Facebook, MySpace and any other site that is not accessible from your location.
Step one is quite simple. Here is what you do. Go to Google Translator by visiting this URL: http://translate.google.com/translate_t# Enter the site you want to visit inside the box.
Doesn't matter what language you want, just make sure the language drop-down on the right-hand side is the language you understand.
Click the translate button. When you get to Facebook or the site you want to see, just login as normal. That's it.
Now, if the previous steps did not work, that means the server has more security. So instead visit this website: http://proxify.com/ Proxy sites let you make your IP address random. The IP address is usually what the server signals when it decides to block you.
That's all there is too it. If the two above methods don't work, try bring a small laptop to school and using your own cable. Plugin your own computer and use the proxy site. Often times, the browser itself will be locked down from making any changes. Your best bet is using your own laptop and plugging into the network. This way the school network will not recognize your IP address, which will most likely let you get in.
