Google's dead link

Just found a dead link from http://labs.google.co.in/
The link to Music Trends gives 404 not found.

Be it http://www.google.com/trends/music
or http://www.google.co.in/trends/music

Any explanation? Is it legitimate mistake?( I am not pointing fingers,donno if it has some explanation..after all its google )

Just innocently logged it..
