Cool visualization and concept. I do wish the colors were on a ramp instead of bucketed. The reason is that it makes 100ms look much worse than 99ms, but equal to 200ms. If you click on us-east-1, for example, the latency to the data centers in Western Europe look quite different with eu-central-1 and eu-south-1 looking completely different even though the latency is only around 9ms difference and eu-north-1 and ap-south-1 look the same even though there's about a 88ms difference! There's some comments here also wondering about the best possible latency for speed of light vs what these measurements are. The problem with this is that c isn't the propagation velocity of information through fiber, it's some velocity well under c and depends on a number of different factors, many of which are unknowable, such as repeater latency and so on. In practice, the best theoretical value is no higher than 70% of c just measuring the velocity of light in a medium as c measures light in a vacuum.
