What happened to www.chess-db.com?

For about the past several months, I’ve been getting the message “service unavailable” from www.chess-db.com. It’s a great chess site with a ton of data and analyses. I’ve tried from different IP addresses, including ones in Europe. Does anyone know what has happen to this site?

I am facing the same problem. So I belive they are down indeed. But the reasons why it is are not clear to me. Would be nice to hear some insights from people who know more.
