If you have a website that is utilizing Google’s PageSpeed Service, Google has announced they will be closing the service on August 3, 2015.  Any webmasters who do not update their DNS accordingly will discover their sites will be down after that date.

After 4.5 years of service, the PageSpeed Service team regretfully decided that the time had come to re-focus their efforts elsewhere and on 5th May announced that PageSpeed Service will be turned down. If you are using PageSpeed Service, you must change your DNS before 3rd August 2015 or your site(s) will become completely unavailable on that date.

Explicit notification will soon be sent to users that we believe are affected, however you should not rely on this! We recommend that you login to the console and look at your list of domains. Anything that shows up as “Enabled” is at risk.

The service didn’t seem to be that popular, but it enabled webmasters to use the service to rewrite their webpages in accordance with best practices, and then this optimized version would be served to visitors. Essentially it is similar to a cached service to optimize webpages for speed and reduce load on the server.

Webmasters need to update their DNS to remove the service prior to August 3 or their site will no longer display to visitors. They have included instructions on how to update this.  For webmasters still wanting to use a similar service, Google is recommending EdgeCast Edge Optimizer  as an alternative.
