There appears to be a routing issue on the VM network.
On the newsgroups, support staff are looking for traceroutes done without the router connected so that they can pass this info up the chain.
If you post your traceroutes in virginmedia.support.broadband.cable without the router attached it should get fixed a lot quicker.

In the meantime using the proxy in your browser should let you access the sites.
