It's a problem with the DNS - the internet's equivalent of a phone directory, that says 'oh, you want AW, it's really at this address' - on VirginMedia for some reason. If I try looking at adultwork.com, I get a 'never heard of it' error, but if I test the link between me and its real address, it's fine. (This suggests to me that AW is not the only site that's affected.)
Use Google to find how to do this (e.g. developers.google.com/speed/public-dns/docs/using) but if you use their DNS servers rather than Virgin Media's, it works...
... mostly. I have had a variety of problems this evening with the connection to the outside world, including stuff taking ages to load, so I wouldn't hope to do any webcamming.
