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 https://developers.google.com/speed/pagespeed/service/Deprecation.

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/appengine/docs/adminconsole/pagespeed#disabling-pagespeed.

The open source PageSpeed server modules mod_pagespeed and ngx_pagespeed and the PageSpeed Optimization Libraries are unaffected by this announcement and development on these will continue.

The PageSpeed team.
