Lots of documentation examples don't even work, e.g.:

GeoGraphics[Entity["SolarSystemFeature", "OlympusMonsMars"], 
 GeoRange -> Quantity[400, "Miles"]]

returns:

GeoGraphics::wdata: "Unable to download data for ranges {{7.41376,29.363},{-145.446,-122.554}} and zoom level 5 from the Wolfram geo server."

GeoBackground seems an issue in Mathematica 10.3.1, the simple Italian map (often used in the documentation) is not drawn at all with "Relief Maps", "ContourMap"; the same when plotting the US map, the error is always what reported above. Changing zoom level or tweaking GeoServer and GlobalTimeout/ConnectionRetryCount don't help. Is anyone aware of this problem? Something broken in the latest 10.3.x? I cannot imagine that in the Wolfram servers there's no relief map of US (and even Italy, of course).
