Today I started researching the "Four colours theorem" and to do so I need data, regions for example. I tried using the following line:

CountryData["Ukraine", "Regions"]

But the result:

CountryData::dlfail: Internet download of data for CountryData failed. Use Help > Internet Connectivity... to test or reconfigure internet connectivity. >>

$Failed

I tried to do this next:

CMD, Ping source

For those who don't understand (because the screen language is Russian) the default source does not respond. How I can change the default source? Mathematica version – 9.0.1.0, OS – Windows 7.

It works from my location right now. Did you try again since then? –  Szabolcs Dec 19 '13 at 23:25
