go to start--> run --> type cmd in run --> then one black window will open(command prompt)-->in cmd type nslookup --> ip "sitename u want to visit".com
it will give u ip, u can type any domain name
Try using the IP address instead of the domain name in the Address bar. ie
instead of typing site name in the address bar type htttp://`12.12.123.12 .See if you are able to get the page. If not, try using a proxy website.Some of the proxy websites are
www.crabcakebatter.com
www.vtunnel.com
www.gpass1.com
http://www.mathtunnel.com

open any of these sites. you will find a address bar inside it. type www.orkut.com in it and press enter.desired webpage should open.
Note - Proxy websites take long time to open the requested web page so have patience.
