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-s…
Author here - The ramping is a really good idea. The current visualization makes a 90ms latency look "good" when in reality, thats totally unacceptable for many applications, especially for things where multiple round-trips need to happen to fulfill a request.
