yep. It was hosted on Geocities. unfortunately many C&V resources were hosted there and it would seem a lot of folks didnt realize that Geocities was closing and they needed to act to save their data.
Hell, I wish I knew that nobody was caring for those resources, I would have gladly hosted any of that stuff....might be good to make a mirror of all the good Sheldon Brown articles just in case Harris decides to stop hosting them.
