Source: did some latency work for a market maker.
Technically speaking those aren’t datacenters, they’re regions. AWS regions can have multiple AZs, and each AZ can have multiple datacenters spread around a city, each with different latency characteristics. This is completely opaque to customers, you don’t really get to choose which one you’re in. There are ways to gain info about it though.

I have red-green color blindness, which makes it hard/impossible for me to distinguish between the 200ms lines. This affects about 8% of male population btw, maybe you can add a color-blind mode, very nice visualization otherwise!
Do you have some kind of an accessibility tool for this? Maybe a whole screen filter that changes colors in a specific way so you can distinguish them?
My comment was meant to raise awareness of this issue with the author of the tool. Many video games, especially the ones with some kind of HUD, minimap, etc. these days have a color-blind mode.

As a quick workaround, you can set a CSS filter on the whole page: Either use dev tools to put a rule `filter: hue-rotate(60deg);` on the `body` element, or simply run `javascript:void(document.body.style.filter='hue-rotate(60deg)')` from the url bar.
Its a bit sad, we have one of the Swedish, actual physical buildings for AWS in my town. But of course the traffic does not exit here, but is instead aggregated between the different sites spread around cities regionally. So no sub-ms latencies for me towards that center. I think the traffic basically went a couple hundred kms before turning back here.
Does your ISP peer directly with Aws?
Obviously the biggest contribution to latency is distance. But there's also some close-ish regions with poor latency because there's not fiber running directly between them (for example, over the poles) Are there an examples of regions which dramatically violate the triangle equality? (That is, where the A--C latency is much worse than the best A--B + B--C latencies)? Just as a curiosity, could you use that idea to "…
You can just look at the map of fiber optic cables around the world: https://www.submarinecablemap.com/ It's highly unlikely there are any non-disclosed undersea ones since they cost rather a lot to lay down.
