Back online with a new dedicated server
My site is back online after a little enforced downtime. I was having real stability problems using a WebFusion VPS and as far as I am concerned their introductory VPS package is unfit for purpose. I'd strongly recommend that you don't attempt to host an Umbraco site with them.
The more eagle eyed amongst you may notice that a couple of posts went missing. I'll just say that I have learned the hard way to check whether my scheduled database backups are running or not.
Anyway, I am back up and running on a dedicated server. Hopefully my site(s) should be a little more stable now.
