Welcome to instability central.
Ok, standard diagnostics. Can you try and download 2 or 3 files from blueyonders gamefiles server @ gamefiles.blueyonder.co.uk. Add the total kbps up, and post back.
Also, run a quick ping to bbc.co.uk and show us the results.
It's possible that you've actually got a fault in your area right now as well.
EDIT: To ping, go to Run, then type CMD. A command Prompt window will come up.
You can then type
ping bbc.co.uk
Post back with the results
