Remember when a site is down - all hope is NOT lost

just put
cache:
in front of a URL on Google
( without the http:// with NO spaces)
to search for any Website that may have been Cached

eg:

cache:search-engines-web.com/

(when looking for the URL of a LINK

right-click --> properties
and select and copy the Url)

Wow. I've used cache in the past when a site was done, but I never thought that you could use it in a search.

Very nice tip.
