i don't know but i hope not.  isp's and enterprises have been anycasting
and/or centralizing their internal recursive dns servers for decades now.
anyone who assumes similarity of network locale or geo locale between the
dns forwarder and the later tcp initiator is being (statistically) silly.
google has no responsibility to warn anybody that such assumptions are
silly.  CDN's probably do bear some responsibility in that area, but:
