On the Search Engine Roundtable, on January 25th, the cache link was deleted from the search results snippet. However, the cache operator is currently functional, at least for the moment. Yet Google said that it will also be decommissioned and cease to exist. "You're going to see cache: go away in the near future, too," he said.

Google stated that you may retain the noarchive tags in place, and Google would still respect them. Sullivan wrote, "But, I hear you say, what about noarchive? We'll still respect it; there's no need to interfere with it. Furthermore, it is used by people other than ourselves.

Sullivan continued by saying that he hoped Google will include links to the Wayback Machine so that people may view the pages' earlier versions. 

"Personally, I'm hoping that we'll add links to @internetarchive from where we had the cache link previously, within About This Result. It is such an incredible resource. I believe it would also be a good fit for About The Result's information literacy aim, as it allows visitors to readily observe how a page evolved over time. No guarantees. We need to talk to them and see how things proceed, which includes individuals well beyond me. But I think it would be nice all around."

The Wayback Machine is a great tool for seeing previous versions of certain URLs, and it's at no cost.
