Here i give you another way, Here is the best way to overcome blocked sites.
Its very simple every system administrators may know it. All of you know about the command ping which is used to find out the link between system to system, The same ping command we use here,

* Goto run -> type cmd or command
* type
ping your blocked site name eg: c:\> ping www.rarun.info

you can find some reply is going on in your command prompt and also you can see a IP Address, just note it and open your explorer and just type as

http://ipaddress and enter

Thats it you can get your blocked sites. You can access this blocked sites through this because the server will block only the domain names but not the IP address of that domain, some times it may be dynamic. So i found this is the best way to getting over blocked sites.
