My previous host, Brinkster.com, managed to completely lose my site. Best of all, they didn't notify me. I just happened to notice about 4 days after it happened. They had no backups. Wow.
I've now moved my site to combination of Squarespace and Office 365. I've got a feeling they'll be a bit more reliable and less likely to have catastrophic failures. Hopefully I'll get content back up in a week or so. Until then, just go to my LinkedIn profile for details about me.
