It's just a domain name, calm down people :X
it's a little more than that.
i guess it depends on whether they've managed to access the servers themselves. maybe they haven't but this is certainly a sign that they're gonna try.
i wonder what they'll do with everyone's holdings. it's not as if it was a dark market. it was an openly accessible site.
Servers are not important but just private keys and bank accounts where their fiat money is.
