Are you facing this kind of problem?


Is this your question? 
 

While I am trying to check the cache snapshot for any of my website, Google is returning the above 403 Forbidden error.




"and You don't run automated queries from our dedicated IP. All computers are spyware / virus free. I'm using the Google toolbar for this query. This happens when I try to check the cache on any site. I've checked maybe 3 or 4 cached pages this hour, could that be the problem? If so, that seems pretty sensitive."


Yes, Many people have same problem while they are try to check google cache.

Trouble connecting: 'We're Sorry' page

Read this first

  • The 'We're Sorry' message appears when Google detects that a computer on your network is sending automated traffic to Google. Automated queries are against our Terms of Service.
  • The error page most likely displays a CAPTCHA (a squiggly word with a box below it). To continue using Google, type the squiggly word into the box -- it's how we know you're a human, not a robot.
If you don't see a CAPTCHA image or if you continue to encounter the CAPTCHA over and over, try these steps in order:
  1. Check for malware on your computer. Malicious software, sometimes bundled with other free downloads without your knowledge, can trigger Google to serve the 'We're Sorry' page. We've suggested some well-known programs below that can detect and remove such applications. Please remember that we have no connection with these companies and can't guarantee their effectiveness.



  2. Contact your network administrator. If you tried the steps above and haven't resolved the issue, it's very likely that a user or a computer in your network is sending automated traffic to Google. Your network administrator may be able to locate and shut down the source of the automated traffic; feel free to refer them to this page. Sending automated queries of any sort to Google is against our Terms of Service. This includes, among other things, the following activities:

    • Using any software that sends queries to Google to determine how a website or webpage ranks on Google for various queries
    • 'Meta-searching' Google
    • Performing 'offline' searches on Google
    Once the automated traffic has stopped, the ban on your IP address should be automatically lifted.


  3. If the problem persists, your network administrator should contact us. If your network continues to experience this message in error, please send us additional information.
