According to the (currently only) NS host:

"We would like to inform you that the UPS located in our data center has malfunctioned. Unfortunately, the repair process will take longer than usual, as the necessary parts for resolving the issue are currently unavailable"

The process has been started to quickly add more nameservers, unfortunately a number of hosting companies housing our DNS have disappeared recently due to more-suspicious-than-usual circumstances.

We recently had to fly someone to another country and hire a private investigator to track down a disappeared host who refused to allow us any access to our disks while he had them plugged into his computers to try to crack into them.

So, while it may just look like the site has been down all day, please spread the word that we're working on a bit more than just an NS record.
