Located in London, I measured the RTT or round trip time to 574,691 random webservers and plotted the times on the globe.

Discovery was done with masscan, measurements using hping and plotting with an old Python script I've revived and enhanced.

~~This is part of the next writeup on my blog, with which I will be posting any of the code I've used.~~

Azimuthal Equidistant Projection shows the equal distances, probably my favorite

Mercator Projection is good too

Thanks!

Is that Azimuthal projection centred on London though? It looks like it's centred in Africa but maybe that's just because the top-left is cropped off because it's all ocean?

Nice catch! I centered there to fit the entire world on the map. Here's centered on London:

Nice. That shows a bit clearer how geography, not just distance, affects latency.
