Just got message from google stating that they will soon disable their pagespeed service soon and warned everybody that used or still using google pagespeed service to remove and reconfigure their website DNS to make sure their site will continue to work properly.
See the mail from Google:
On July 28, 2011 we announced PageSpeed Service, an online service to automatically speed up web pages. In the last 4½ years, PSS has delivered millions of pages for thousands of sites, all for free. While a number of sites continue to enjoy the benefits of PageSpeed Service, we see much broader adoption of PageSpeed technology through our open-source products and have therefore decided to focus our efforts on improving those.
Today we are announcing that PageSpeed Service will be turned off
on 3rd August 2015. Users must change their DNS to point away from
the service by this time, or their sites will cease to function.
We have created a migration page that includes assistance for
changing DNS as well as information on other ways PageSpeed technology
can be employed on websites. Please see
At the same time we are also announcing the deprecation of PageSpeed integration with Google App Engine. If you are using PageSpeed integration on Google App Engine, it will continue to function until 1st December
2015, after which PageSpeed optimizations will no-longer be applied to your app. No action is required on the part of App Engine users;
after this date apps will continue to operate, except without the benefit of the PageSpeed optimisations. Users that wish to pre-emptively disable PageSpeed can follow the instructions at https://cloud.google.com/
The PageSpeed team.
Now you have seen the announcement from google and its time to reconfigure your DNS to point to your own server and failure to do that will result errors.
