A lot of people got used to have total freedom when they use the Internet because it was one of its principles which some countries, internet providers or even employer try to break. Of course the government should block sites which are illegal which offer pornography or terrorist. But sometimes it would be wrong to block such websites like facebook on your work. Of course a person should think all the time about his work. But when he has a small break it would be fair to drop a little message in his Twitter or Facebook. But such websites can be blocks. In this case the only solutions of this problem will be to use Virtual Private Network. The main advantage of this technology is that it helps to overcome practically all restrictions and get access to any websites that you like. You can even use OpenVPN which can be free for everyone. Using this technology you will be able not only to unblock Facebook and even torrent anonymous and nobody will be able to find out any personal information about you.
