Google announced it is dropping its PageSpeed service last week. Don’t panic, though, the search engine giant will be replacing the feature with a “broader adoption of PageSpeed technology.”
This is good news for online businesses across the board, perhaps other than those already subscribed to the Page Speed service. Now everybody will have equal benefits.
Furthermore, if you are currently using PageSpeed you will need to update your DNS by 3rd August 2015, otherwise your visitors will not be able to access your website.
You can find more details about migrating PageService on Google developers.
