I never even thought about this before, but what kind of hardware is a root level DNS server like 1.1.1.1 or quad 8 run on? Are they all roughly the same, or do they take different approaches to the load?

Dang. They do it all in one Pizza box. I figured it would be a whole rack per unit.

I’m actually surprised that they use some beefy servers. Like, Google famously use shitty and cheap commonplace hardware, but in large numbers, so it’s easy to replace when it croaks.
