title: 403 Forbidden in Google map api v3
body: <p>As it is stated that Api key is not needed in Google maps v3 but using<code>http://maps.google.com/maps/api/js?sensor=false</code> I was only able to use maps for 3 days then I started getting 403 Forbidden error. I only send about 300-400 requests per day so that shouldnt have been a problem.</p>
  
  <p>Then, I decided to get the api key and used it, it also worked fine for 3 days; after that it generated same 403 forbidden error.</p>
  
  <p>Can anyone please guide me if I am missing something or getting business plan for google api is the only way?</p>
  
  <p>Thanks</p>
