I seriously doubt it was wupload who did anything to "unblock" premium users. As I said, some internet providers in the UK are blocking filehosting companies. Not all.
And I have a friend, premium user in the UK, who has also been unable to use wupload, fileserve, filesonic and megaupload for 2 days already.
Well as a user from the united kingdom, i can say megaupload works fine,
And i still stand by my statement, If you doubt it you must have a reason to doubt it so please explain, My isp is not blocking it, i tried from many different places and its just for ips originating from the united kingdom.
