Why are some areas grayed out on Google Maps?

Sometimes when you scroll across a Google Map screen you'll see blocks of grey. Usually this occurs when the map is set to satellite view and the application struggles to load the data fast enough. However, sometimes this phenomenon occurs in map view if Google doesn't have access to the right data.
