One of Google Search’s oldest and best-known features, cache links, are being retired. Best known by the “Cached” button, those are a snapshot of a web page the last time Google indexed it. However, according to Google, they’re no longer required.
“It was meant for helping people access pages when way back, you often couldn’t depend on a page loading,” Google’s Danny Sullivan wrote. “These days, things have greatly improved. So, it was decided to retire it.”
I’d say things are much worse than they used to be. Sure, in the past sites would disappear or completely fail more often. But, because most sites were static, those were the only ways they could fail. These days the cache feature is useful for websites that have javascript bugs preventing them from displaying properly, or where the content-management-system still pretends the link works but where it silently just loads different content.
