How to access blocked websites at schools , office and unblock restricted sites

It is very annoying to see some sites are blocked at your school and office, especially social networking sites. There are ways to bypass these restrictions. There are many proxy sites which allows you access. Few of them are listed below. Your administrator may not notice these because they uses different IP address than the one which is assigned to you by your strict network administrator.
