If they Fed's have it, that could be a different story, but if that's the case, why did someone take the time to replace the cloudflare page with an official looking "Down for maintenance" page? If they FBI took it down, they usually like to brag about it.
FBI haven't found the servers probably, yet. They only got one admin. They'll make him squeal. That's very easy. 2 choices.
1-Alex tells them everything, he stays in jail for the rest of his life.
2-Alex tells them nothing, he still goes to jail but he'll get some extra there;)
