If you've built global geo-distributed networks, then you should know that anycast will not distribute traffic evenly across the pops. Most likely the USA pops do 10-100x the traffic of many of the others.
My guess is that some pops are handling 5M+ req/sec. That's a pretty impressive feat of internal load balancing.

- jedberg 3y agoYou did but you hand waved right over it with "rough enough to plan for". Also I think it's important to call out the high variance specifically for the people who are not network engineers. I think you're being misleading with your analysis.
- theideaofcoffee 3y agoEven with an order of magnitude (or two!) difference it’s still an easy problem, especially for DNS.
- junon 3y agoDNS requests fit within most standard MTUs (1500 bytes) over UDP. Almost all of it can be warm cached, and the datapoints are highly compacted and can be sorted offline. I agree with the OP, it's not really that high.
