I am surprised that no one has mentioned the most obvious alternative: Bing Cache.

It is not as complete as Google's, but it is usually good enough.

Yandex also has a pretty extensive cache, although recently they seem to have disabled caching for reddit. Otherwise it is good for finding deleted stuff, I've seen cached pages go as far back as a couple of years for some smaller/deleted websites.

I only ever used cache to find what google thought was in the site (at the time of crawling) as these days it is common to not find that info in the updated page. For everything else, there is the Internet Archive.

Thanks! I never go to Bing but I probably will now.
