    I hadn’t realized we’re not talking about the authoritative servers saying who runs each domain under .com (run for profit by Verisign) but the ones another step back that tell you who serves .com and other TLDs. So root.zone is a ~2MB text file.

    Chrome plans to get rid of its probe that’s causing disproportionate root-zone traffic. But if there’s something to do on the serving side, seems noteworthy that making the data available from more places is much more about logistics/security than the size of the dataset.
