I saw some Google IPs in the logs, and confirmed our requests are triggered
by user requests via our free public DNS servers (8.8.8.8).

I suspect something is trying to detect whether there is nxdomain

This started quite suddenly, which excludes a client-side binary change.
 Could be something baked into the javascript of the website, though....

That rate is very low, which makes it somewhat unlikely this is an
intentional DoS (which would be 1000 times larger even for a weak attack).
 I'm guessing this is either accidental or is the result of bad javascript
on a website.  Tracking down the source seems difficult, but I'd be
interested in hearing what you find (and how you figured it out!).
