really cool tool, thanks for building this.

#62Earlier quoted context omitted.
Author here. This is great feedback, thanks.
Idea: select a data center by default (i.e. us-east-1) to make it more clear. Bonus: select the nearest data center based on the user’s IP :)
Nitpick detail: us-east-1 (and all other availability zones) are also not a single datacenter by definition. The can also spend several
Re: AWS data center latencies, visualized
#63How did you choose which datacenters to include? For example, eu-south-2 (Spain) is missing. The reason I know is because I worked on a project that required latency to be under 30ms between datacenters, and we had to use eu-west-1 (Ireland) and eu-south-2. Turns out that latency is closer to 42ms, mainly because there are no undersea cables between Ireland and the continent (they only go to England, then they have t…
There are good few DCs missing on that atlas

Yeah the new(ish) Melbourne region is missing too
Re: AWS data center latencies, visualized
#65Obviously 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 "infer" which data-centers are most likely directly connected by fiber, and show only the likely fiber connections?

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.

#67I 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!
I don’t see any lines at all. Just blue dots repeating the data centers. Very confusing.

Click dots.

You have to click one of the data centres

Tap a blue dot.
