I'll let my friend know. It's his domain and hosted on his server. This was the first time I've visited the site in about a year and I happen to have been in Chrome when checking if it was still live, so it worked fine. I doubt he'll care or make any changes since I'm pretty sure nobody visits it anymore. Thanks for the heads up though!
