Hi Eric,
Thanks for digging in to this, its very helpful. And sorry to leave you
hanging without a response.
At the time, when geoIP was unable to determine what city / country /
continent, the system would fail and spit out a null-pointer-exception (NPE)
and be generally unfriendly.
So it was an improvement to keep the system working, and say "unknown
country" instead of failing. However, all of these unable-to-be-determined
don't indicate that a secret unknown civilization has been visiting your
site, such as Atlantis, but that the system couldn't figure it out (timeout
for reverse DNS too short -- better in 1.7
DS-628<https://jira.duraspace.org/browse/DS-628>,
no data for IP's reverse geolocation, ...) .
However, it might be an improvement to just skip from showing you how many
not-available's there are affecting an entry in the stats, then to slap an
unknown on it.
