Same for me mate.
But i think we figured that it is DNS problem for me.. as it is satellite connection and handles things differently apparently. So in 24hrs it should be working again for me.
If you are not on a Sat connection.. Have you tried clearing cache/history from your browser?
Also try Start > Run > CMD > type "ipconfig /flushdns"
you might need to run CMD as Admin, in that case Start > Programs > Applications > Right click on CMD and choose Run as Admin.
