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.

let i = 0; setInterval(() => document.body.style.filter=`hue-rotate(${i++}deg)`, 16); Disco mode! (better to use requestAnimationFrame but I'm lazy atm)

  let i = 0;
  function bump() {
      document.body.style.filter=`hue-rotate(${i+=2}deg)`, 16;
      requestAnimationFrame(bump);
  }
  requestAnimationFrame(bump);

Low-bandwidth/low-latency people tend to also demand high reliability and consistency. A low-orbit satellite network might be fast but, because sats move to quickly, cannot be consistent in that speed. Sats also won't ever connect data centers other than perhaps for administrative stuff. The bandwidth/reliability/growth potential just isn't there compared to bundles of traditional fiber.

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!

It's sad that this is the top comment for the post. Many people have stopped posting their crappy work online due to harsh comments like yours. There's no easy reply to your comment. Maybe we should be less critical specially with "Make it fit for my workflow" type comment, and more so if it is built by some random guy in their free time, and not say a project which is asking money.

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 "…
