Google has now totally disabled the Google Cache from completely working. Earlier this year, Google removed the cache link from the search result snippets. Then a couple of weeks ago, added links to the Wayback Machine. Now, the direct link to see the Google Cache has been fully disabled.
I was super annoyed when they first took away the links. "Pages are more dependably available now," is such a lazy excuse. Storing the cached content probably wasn't even that expensive for them, as it didn't retain anything beyond basic html and text. Their shitty AI-centric web search was likely the main reason for getting rid of it.
