title: Create a custom DNS error page
body: <p>I am building a new extension and I would like to customize the default error page in Google Chrome. I have gone through the "Override Pages" documentation <a href="http://code.google.com/chrome/extensions/override.html" rel="noreferrer">here</a> but have yet to find anything about customizing the page I have specified.</p>
  
  <p>Any suggestions are much appreciated. Thank you.</p>
  
  <p>The error page I want to customize is:</p>
  
  <blockquote>
    <p>This webpage is not available</p>
    
    <p>The server at <strong><em>_</em>___</strong> can't be found, because the DNS lookup
    failed. DNS is the network service that translates a website's name to
    its Internet address. This error is most often caused by having no
    connection to the Internet or a misconfigured network. It can also be
    caused by an unresponsive DNS server or a firewall preventing Google
    Chrome from accessing the network. Here are some suggestions: Reload
    this webpage later. Check your Internet connection. Restart any
    router, modem, or other network devices you may be using. Check your
    DNS settings. Contact your network administrator if you're not sure
    what this means. Try disabling network prediction by following these
    steps: Go to the wrench menu > Options > Under the Hood and deselect
    "Predict network actions to improve page load performance." If this
    does not resolve the issue, we recommend selecting this option again
    for improved performance. Add Google Chrome as a permitted program in
    your firewall's or antivirus software's settings. If it is already a
    permitted program, try deleting it from the list of permitted programs
    and adding it again. If you use a proxy server, check your proxy
    settings or contact your network administrator to make sure the proxy
    server is working. If you don't believe you should be using a proxy
    server, adjust your proxy settings: Go to the wrench menu > Options >
    Under the Hood > Change proxy settings... > LAN Settings and deselect
    the "Use a proxy server for your LAN" checkbox.</p>
    
    <p>Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's
    DNS address.</p>
