As you know, Google originally announced SSL search back in 2011 where it would impact "less than 10% of their users." Now, it is impacting over 90% of users and thus showing [notprovided] to webmasters and marketers about 90% of the time.
That being said, network administrators and ISPs can do something about it. You can force the non-SSL version of Google to your users. How?
As Jessica Schwartz from Google (no relation), said in a Google Web Search Help thread, "there is an option for No-SSL." She links to this page for schools that specifies the configuration change the network administrator needs to make to prevent SSL searches.
To utilize the no SSL option for your network, configure the DNS entry for www.google.com to be a CNAME for nosslsearch.google.com.We will not serve SSL search results for requests that we receive on this VIP. If we receive a search request over port 443, the certificate handshake will complete successfully, but we will then redirect the user to a non-SSL search experience. The first time a user is redirected, they will be shown a notice that SSL has been disabled by the network administrator.
Customization and personalization is dependent on SSL availability, thus some features may be affected. Utilizing the NoSSLSearch VIP will not affect other Google services outside of Search. Logging into Google Apps and authenticating to different services will continue to work (and will occur over SSL).
I see no reason why this has to apply just to schools. You can probably do this at your home and your company. And I am sure ISPs can do this as well. Will it happen? Nah, but we can dream.
