Oops, somebody forgot their whois privacy when they renewed their domain.
I hope that's not the owner's real info...
I seriously doubt the owner of the visable website is directly connected to whoever runs the Silk Road hidden service on Tor.
Oops, it gets worse. Whoever bought the visible website is hosting it with a US company that is reselling server4you.de services. If someone was silly enough to put the Tor hidden service on that server, thinking it safe since it isn't in the US, they're in for a rude awakening when the US company they're paying the bill to grabs the server's data and hands it over to the FBI. I sincerely hope that whoever is running the show didn't make a mistake like that.
