I'm surprised 60 billion DNS queries is only 41% of the daily norm. With a billion people between the US and Europe alone - the vast majority of which use the world wide web directly multiple times a day (nevermind other online services) - and the amount of domains a typical website loads resources from, I figured daily DNS queries would have broken into the trillions by now.

I suppose that's probably thanks to caching, dedicated apps for many websites, and most users sticking to a relatively small selection of websites.
