>As Admiral Grace Hopper would point out (https://www.youtube.com/watch?v=9eyFDBPk4Yw ) doing distance over network wires involves hard latency constraints, not to mention dealing with congestions over these wires.

Even accounting for CDNs, a distributed system is inherently more capable of bringing data closer to geographically distributed end users, thus lowering latency.
