none of the rootops puts our terms of service on the root-servers.org
web site, because it might look like advertising. but anyone from isc is
happy to talk about it; for example i can say right here right now that
we go where we're wanted: we rely on local sponsors. we prefer internet
exchanges but we've done some inside-ISP f-root installs when there
either isn't a local IX or the ISP is huge. we like to control our own
BGP, so the inside-ISP installs will usually not be offered to that
ISP's peers or transits, only to their customers.

other rootops have their own wonderfully diverse criteria; that's a feature.
