Where did the free site http://www.mahjongg.ch/ disapper to?

I've been playing solitaire mahjongg at the free site http://www.mahjongg.ch for several years. Suddenly, today (4/23/07) the site disappeared -- anyone know where it went? Tried tracking it to the domain site, but it's all in German. Translation is not so great, but I think it's for sale again. Last time it was for sale, you could still access it. I'm on a Macintosh computer and can't use any of the other free sites -- anyone know of other Mac-compatible Mahjong sites? Thanks for the input!
