It is over.

Probably you are right but I still have some hope. There is old version of website stored on Google Cache here http://webcache.googleusercontent.com/search?q=cache:http://mail.coinsmarkets.com/&gws_rd=cr&dcr=0&ei=tzhnWsHuEI2WsAegvLKQCA
And this version is just one day old so the website was accessible recently, that's why I still have some hope. Their last news were: "We are checking with different hosting now. Process taking longer than expected with fixing DB , All coins are safe ."
