A couple yrs ago Google announced that it was discontinuing use of the caches. They were directly accessible and also accessible via 12ft.io. So loss of 12ft.io was expected at that point. But strangely I continued to enjoy access well after that announcement. I wasn’t sure what happened; wondered if it was just that Google discontinued caching new pages. It was a bit hit and miss.
Google’s wording was bizarre because surely Google still needs the cache for indexing. I wondered if Google made a false statement where the reality was just removing public access to the caches, not actually discontinuing use of the caches.
