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?

No I don't. It's actually not a big deal in day-to-day life. People often go "But how the hell can you drive if you can't distinguish red from green at the stoplight?"... in reality it's more nuanced. As another comment already mentioned, perception varies across even among colorblind people. I find it hard to distinguish R/G if the colors are not fully saturated or in low-light situation. Also the brain knows that "…

Yeah I’ve seen colorblind modes in a lot of apps. It is great for those affected. And probably not a huge hassle to implement anyway.

But I was curious if one needs to rely on the application developers to deliver a solution or if there was a generalized filter or whatever that would work always. Maybe like screen readers, those work fine if the app does not do something horrible. But with some help from apps, they perform much better.

Us-east-1 is hard to beat. Close to the network centrality of the of the internet, low latency to both the west coast and Europe.

My knee jerk reaction was to comment that this is an America-centric thinking (I live in eastern Europe, us-east is not that great), but... After consulting the map, it really looks better than the other options (of course assuming you care mostly about Europe, Americas, and don't want to piss off Asia too much)

Just curious, why is there no us central or us texas region? It could maybe be useful.

Azure has Ohio and Texas, but you'll probably not be able to provision all the machines you want so it doesn't really matter.

I think a lot of people are sleeping on the benefits of hosting workloads in these regions. Many finance, banking & insurance companies have already taken advantage. Most of your credit card transactions are handled by data centers that live ~barycentric to the continental US. Much of small US banking tech happens in places like Missouri.

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.

The easy reply is "thanks, I learned something today!"

I think this an uncharitable take – the parent comment is just proposing an improvement that would really help them given their colour-blindness (they also say they like the visualisation). Personally I find part of the reason for putting things on the internet is to allow other people to use them and obtain their feedback.

I worked at a military company and we made a SIEM tool to use at government facilities. Our Director, which was an ex-colonel at Miltiary IT, found that login screen is too plain and we need to have a world spinning. So we've implemented the end of Terminator 3 nukes over globe screen in WebGL to please him. This reminds me of it.

Anyways, although this looks cool, it'd be much more easily understandable in a 2d map instead of a rotating one.

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.

Nice hack, thank you! :-)

Can also use Chrome Extentions like Colorblindly to change all the colors. Tested it on the webpage now (I am not colorblind) and I see that the colors change: https://chromewebstore.google.com/detail/colorblindly/flonia...

Oh shit! Thanks. Good point. That actually makes it more plausible, as K is smaller.

1/2 c in circuit boards (FR-4), 1/3 c in cables, two useful numbers to remember.

Thanks, nice! But wait - so we have

1/2 c ~ 150 km/ms in circuit board.

1/3 c ~ 100 km/ms in cable. And...

2/3 c ~ 200 km/ms in fiber?

I'm a bit confused about difference between cable and fiber heh :)
