At one point, Google took on the difficult position of caching all the web pages it searched for. These pages became an alternative way to load a website that wasn't working or to see how it looked before it changed. However, now Google has decided that it will no longer cache pages and people will have to rely on loading the page directly.
According to its representative Danny Sullivan, Google started with the feature at a time when the Internet and servers were not as perfect as they are now, and people often had trouble loading a page because it did not work. However, that has already changed, and that's why Google is going to disable the feature.
However, most people don't see the option to view web pages from Google's cache anymore. This option was available in a drop-down menu next to every Google search result. When Google searched for anything and crawled the pages, it cached them, resulting in it having a backup of basically the entire internet. In Google's data centers, these backups alone took up countless space, and that's why Google decided to free up a lot of space on its servers by turning off this feature.
