Can’t get a particular page to open? Just add
cache: in front of the URL and Google’s cached copy will open instantly.
Nick Douglas, writing for Lifehacker, pointed this out yesterday and it’s kind of blowing my mind. It works in every browser, provided Google is set as the default search engine. Some sites block Google’s cache from working, but other than that this works.
Cached pages are very useful when a given site is down, or even when a specific page has been deleted. Give this a shot next time you come across a 404 error, or otherwise can’t open a page you know used to work. It just might give you access to the information you were looking for.
