Duane Wessels did a good study some time ago of queries to the root. I believe over 99% were bogus, not real queries for resolvable things.

In some cases perhaps. In our case, we typically install eight at each location, and we’ve passed two hundred locations now. So this:

We provide them to make the root more resilient against DDoS, and to reduce query latency. But we’re a non-profit which exists for that purpose, we don’t derive any revenue from it, and our finances are publicly audited. For-profits require revenue, and there’s certainly a market for pcaps taken from in front of root servers.
