The folks in the Google Maps Help forums and Local Search Forums are not happy that Google is no longer showing local boundaries in Google maps.
Starting about a week ago, the boundaries lines from Google Maps disappeared. One maps user said "I am unable to find the local area boundaries, usually every time type the name of local area followed by sub-district name and regency name the result was the local area complete with boundaries (red line)."
One shared a before and after shot.
Before:
After:
Google has not yet confirmed if this is a bug or feature. Meaning, did Google remove the boundaries on purpose or if it was an oversight and it will come back soon.
I believe local SEOs used this also to figure out where their clients might rank within a city center limit.
