I recently came across:

https://ipapi.is/blog/ip-geolocation-accuracy.html

which analyzed 10 geolocation DBs for accuracy based on ground-truth.


I assume it is biased and many here will point out the holes in their 
analysis.

Nonetheless, it would be nice that some neutral Internet measurement 
organization (of which there are a few) would take up this effort on a 
yearly basis.
