Nanofate.us has come back up three days ago. However, unfortunately, it is still being fixed, that’s why it would still be occassionally down for the meantime. The site will be back up soon, hopefully.
And also, apparently, the site has been getting hacked by Thai Hackers, and repeatedly deletes the site for a period of time. So they’re apparently in a bit of a danger. But don’t worry too much, I’m sure Nanofate.us can survive this and they’ll be back up soon.
