Can only connect to some websites ???

Tonight I’ve only been able to connect to some websites i.e. I can connect to, but not or ??? Last month I was upgraded to 10Mb cable on VirginMedia but I was able to connect to all sites until tonight. The strange thing is 2 friends of mine are also with VirginMedia yet they can access the websites fine? We all live within 5 miles of each other.

Has anyone else experienced this problem?

This is going to mess with upgrading to Intrepid Ibex which is due out in a few days 🙁
