Site administrators will have three months to change their DNS settings to ensure their websites remain visible after Google today announced the closure of its PageSpeed service.
PageSpeed launched more than four years ago and offers websites optimisation services to speed up the loading of web pages.
But from August 3rd, PageSpeed will cease to exist, joining a range of other Google services put out to pasture, such as the Code source repository currently being wound down.
"After four and a half years of service, the PageSpeed service team regretfully decided that the time had come to re-focus their efforts elsewhere," Google wrote.
The company warned that sites using PageSpeed will need to update their DNS settings before PageSpeed ceases to operate in order to keep their websites and domains reachable. It offered instructions for site admins on how to migrate.
"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," Google said.
PageSpeed plugins and third-party implementations will continue to be avavilable.
Site admins and developers can continue using the majority of PageSpeed features through the open-source Apache server, nginx, and PageSpeed services offered by hosting providers.
