BUTT, root servers are NOT recursive or caching, they serve a very
small limitited set of data that changes at low frequency (I am
not sure of the current rate of updates, but it use to be only
once daily.)

Anyone can bring up there own replicate of a root server locally,
I do, and have for 2 decades, its a rather trivial thing to setup
and maintain.  But unlike a root, I also turn on recursision and
caching.

Again IMHO, a caching recursive any cast server ala 8.8.8.8 would
be far more useful than just a stock "root server."
