Honestly, I think last I knew (a few years back) there were ~8 million recursive resolvers, so even if you had them all coming once an hour to fetch that 1.4MB you are around maybe 25Gbit/sec which is well within the range of a modern server to transfer. That assumes everyone hits the one machine too, you spread it out and it’ll be lower. There’s a lot of other queries I would worry about more than these, and the bitrate we see daily at $dayjob is much higher than this. I do like these questions, but also if the whole world could be served from a single machine (in theory) with 100Gbit/nic then it’s honestly not that bad. - Jared _______________________________________________ DNSOP mailing list -- [email protected] To unsubscribe send an email to [email protected]
