Just a small quote regarding K-root (DNS) from the good folk at RIPE [1]:
"Configuration management of our K-root server platforms is now
automated almost entirely, using a customised tool set based on
Ansible. This eases the day-to-day operations effort for our
servers, for K-root as well as other services."
I thought you may want to know.
