Russian users of Google Maps, who use the service through Google.ru, will see that Crimea is wholly a territory of Mother Russia. That black line is a border — the same style that marks all 1,426.07 miles from the Black Sea in the south to Belarus in the north.
Americans who visit the region on Google Maps through Google.com will see the disputed border — where it seems the two countries are still working things out.
But what for Ukrainians, who lost Crimea following Russia’s annexation last month? Nothing to see here. Users on Google.ua will hardly notice a nearly invisible grey dotted line that etches its way between Crimea and mainland Ukraine.
