This all fits together as Mirjam and Nick’s info points out.

From terrestrial fibre related issues to submarine cables we have many moving parts that relate to bottlenecks and throughput and bandwidth.

We would need to define Internet-wide distribution of X as the variables within some regions is enormous.
