On the day of winter Solstice in 2012 Whistleblower 51 published an article in which I disclosed a secret of the Russian government in connection with the nuclear missile control system called "Perimetr" and the secret underground complex under Mount Yamantaw. On August, 04 of 2013 I discovered that my site had been hacked and the article with that information reverted to its draft form, containing no classified information. So to you hacker(s) out there: it's a bad idea to hack into information that accuses people interested in shutting such information down, because if the owner has a backup, you're disclosing yourself.
All the awesome videos and the interactive map are gone, but the truth re-emerged on the surface again. Here are the backup scans of the article's printouts. Good luck hacking into the piece of paper, FSB!
