Update #1: Silfax has come forward with updated information (see below). Currently it's my personal opinion that he may not be the one who stole other people's money, but he does bear the responsibility of using sloppy implementation and lack of good security practice.
Update #2: Silfax has restored the site and customers are able to withdraw 58% of the balance before the theft incident. Page down for more details.
What happened:On Nov 23, 2013, bit-u.com went offline. A few hours later Silfax claimed his exchange bit-u.com (previously Coingrounds.com) was hacked, BTCs were moved to a different address by an unknown user, PTSs was not mentioned. He also claimed some one got access to the (DigitalOcean) hosting account and deleted the VPS instance after stealing the money.
Since he made the claim on bit-u.com chat box, he hasn't been in any contact with his customers, leaving all victims holding the bag.

Silfax hasn't made any contact with exchange customers for almost 24 hours after he last appeared in the chat, nor did he provide any evidence to support his claim, no trust should be given to him, bit-u.com, coingrounds.com, or possibly DigitalOcean VPS hosting.
I'll update this thread when more information is available. Feel free to add your claim or evidence.
Edit: added time and fixed typos.
