The Nanobox was down for a few days due to some complication, but it's back up now. The problem was I stupidly decided to modify /.htaccess using an HTML-based administration system and broke the file, thus creating an internal error for every request on the site. I tried to fix it through SFTP, but something was screwy with the permissions and I couldn't fix it. At the time, I was at my dad's house for a week, but now that I'm back I was able to fix it. No worries, mate.
