hell, i'd like to filter on that on the websites of fiber providers. they say, "we can't see what areas are covered. we can only see if a specific address is available." i've seen in the days of ADSL that one side of the street was able to get service, but directly across the street was not. Something about how the lines across the street are clustered in older equipment blah blah blah. So they telco doesn't know what equipment where without that specific address lookup.
