Were you one of those affected by the Managed.com attack that took down their services last November? I heard a lot of people in the DNN world were affected by it. I never used Managed.com myself, so I was not affected by their outage, thank goodness.
I myself had a similar incident with a VPS of mine last year, but luckily I had offsite backups. I only lost a day of data in my situation.
I really do wish that there was a way to contact this vendor that vanished.
