Danny Sullivan, a Google Search Liaison, announced on X (formerly Twitter) the removal of the ability to view a cached version of a page by adding "cache:" to the URL in search. Soon it will stop working completely.
The cache operator is only available for web searches. It allows you to find a cached version of the page that Google generates so that users always have access to the content, even if they cannot navigate to the site. To use the function, you must enter cache:example.com/your/page.html in the address bar, for example - cache:.com. Then you need to click on the three dots or arrow next to the result to see a link to a copy of the page saved in the cache.
As Sullivan notes, the cache operator: is one of Google's oldest features, necessary to ensure that users don't lose access to data when a site is unavailable. Nowadays, such situations practically never happen, so it was decided to abandon the function. Sullivan hopes that in the future, Google will negotiate with the Internet Archive to integrate links to copies of sites from The Wayback Machine into the “About this result” section.
