Erpz.net was briefly gone yesterday for almost the entire day because the host, Siteground had some harddisk damage on the server where this site was hosted and everything on the site was wiped out. I tried accessing the FTP and found that everything, including the http access were gone.
Fortunately it came back up in the night, when I just reached home and wanted to send in a support ticket to complain about the problem. I hope this never happens again.
