The data is really useful, and the globe is visually impressive, but it feels like it'd be more practically useful to have a flat world map that shows all the data centers at once and makes it easier to read the lines without them getting excessively close to each other.

This was popular in ham radio, iirc:

Ah, this was what I tried first, and it didn't do anything, but now it does seem to be doing something. That makes sense now, thanks.

Same... didn't work until I moved the globe a bit. I thought the site was broken, or getting the HN hug of death.

Random fact: I did some planning around this for a client a while ago. While measuring the AWS latencies I found I could get approximate latencies (within 10%) by measuring the rough undersea cable length (km) and dividing by 150. While not overly surprising, it was very consistent. Edit: I think it was actually 155

That reminds me of the story of the 500 mile email ( https://www.ibiblio.org/harris/500milemail.html )

I read this yeaaaars ago. I'm about to re-read this, but before I do, I think this was the article that installed a little goblin in my brain that screams "TTS" in instances like this. I will edit this if the article confirms/denies this goblin.

EDIT: mostly, probably, sort of.

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?

This is such an easy thing to overlook for those of us that don’t. Red/green tends to be a default selection, perhaps because of traffic lights?

I started putting myself in the shoes of a family member who is in the 8% and now i spend more time trying to pick better color schemes

Color-blind man here. While I think it’s important to consider color blindness when choosing colors, it’s not actually 8% of men who would have trouble distinguishing the two colors. That number is somewhat lower. Perception of color varies even across colorblind people so just because someone says it works for them doesn’t mean it will work for someone else, and vice versa.

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?
