Google publishes that information at
https://developers.google.com/speed/public-dns/faq#locations
and chances are this gives you a list that might be used to roughly
determine their clients geolocation in case your authoritative server is
not yet EDNS client subnet enabled. ( http://www.afasterinternet.com/ )

cluster closest to you. Also it should be easy to write something up that
returns the recursive Server IP that queried for a certain qname as a TXT
record or even automatically the matches from that list.

best regards,
