Am I misreading the article or does it show that this accounts for 50% of the dns traffic the root servers see? I don’t think that’s minor.

  It's the most popular implementation of what is by a very wide margin the most popular and important app on the Internet. What percentage of traffic would you have assumed it represented?

    Less than genuine lookups? Even if all the world's DNS traffic came from Chrome, probe lookups are taking 50% of all root server traffic just to confirm NXDOMAIN over and over.

      The browser confirms it at startup and when DNS settings change, not "over and over"; the "over and over" comes from the fact that zillions of people use Chrome. Serving the zillions of people who actually use the Internet is the job of the root servers. If they wanted to serve a small number of requests, they could go be the authority server for zombo.com instead.

    A lot less than that. The point of the hierarchy of DNS caching is to keep traffic at the root (and points of authority) low. I would assume that the vast majority of traffic to/from root DNS servers to be due to access by caching resolver daemons not individual user applications, especially not one particular user application (no matter how popular).
