That's me not knowing how the DNS stuff is currently handled, thanks for
the info.

Maybe we should have a sandbox VM that gets reincarnated (wiped of crud,
started from new) every once in a while for things like testing/piloting
new ideas. The nice part of experimental stuff is that we can turn those
VMs on and off whenever we feel like it - Though there needs to be a
good gatekeeper to prevent proliferation.

I'm going to see if they can bring 1 server online sooner rather than
later so we can get started and they play shuffle if they need to update
some things.
