RE: How common is lack of DNS server diversity?
More interestingly, how many root servers allow recursive lookup?
a quick looping probe shows that none of them do, nor the gTLD servers (phew!) although L.ROOT-SERVERS.NET and H.GTLD-SERVERS.NET are unreachable from my view. Preparing an accurate list of all TLD servers glued in the root zone will take a little longer.
I was taking about root servers at ALL levels, not just the root.

Perhaps you are using the term "root servers" in a different manner than I am used to. For me: "Root Server" = a DNS server for the zone "." in the Internet. What do you mean by "root servers at ALL levels, not just the root." That construction just does not parse. --bill

I believe the phrasing Roeland may be looking for is "how many *zone* servers (ie: authoritative servers, not customer resolvers) allow recursive lookups", no, Roeland? Cheers, -- jra -- Jay R.
