My ISP is World Exchange.
I have tried going to www.isohunt.com and the page constantly says 'connection interrupted' on both my PC's. Other websites are fine.
I then managed to browse to the exact same website by turning off wifi on my iPhone and only utilising the 3g connection through Vodafone.
Is my ISP blocking this website and are they allowed to? The website to the best of my knowledge is not illegal.
