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.
