Service Area Polygons interpretation

Hi,

I am solving a service area polygon with a roads network dataset and attached is the result.
Breaks - 250, 500, 750, 1000 miles.
The polygons in the image are only drawn north and south of the facility.

Polygons are drawn incompletely for certain central geographic regions, and are very poor for coastal cities.
There are regions with huge gaps in polygon fill in. There are clearly roads bounded on all sides for these large areas, so I???m not sure why the graphic cannot
show this.

This kind of results when testing with Esri street data too.

Any logical explanation to these results?

Thanks.
