The version of MaxMindDB being shipped with discourse seems to have got outdated (it reports my IP from an incorrect city/state) whilst, checking the same IP against their GeoIP2 demo, It reports the Correct State/City.
The effect for the same is visible here on meta Under the recently used devices section.
That’s what we do now (we ship MaxMindDB with the Docker image), but doesn’t seem to be good enough because the MaxMindDb updates more often than our image.
