This seems like data has been lost from servers hosting sites/services.

Since Gandi is mostly known for domain registrations and DNS, I'm curious if you (as an individual who hosts websites/online services somewhere on the web) backup your site's DNS records periodically (or whenever they're changed). What if your authoritative name server lost data and all the caches of those records across geographies expire while you're asleep/away? If you do back these up regularly, how do you do it in an automated way on a *nix system? I found this article [1] when I searched about this, but it's not a simple shell script. The scripts that I did find on some of the Stackexchange sites seemed to have specific subdomain names hardcoded.
