A similar problem would be created if a web server relied

Do you (or somebody) know of recent numbers of what percentage of
domains have all their DNS servers in;
a) same subnet
b) same AS
c) same geographical "zone" (faultline, floodplain, coastline, etc.)
Obviously if everything served by the DNS is co-located in the same
failed facility, it does not matter that much if the names resolve to IP
addresses which are unreachable anyway.
