It was while i was surfing the Internet, i found this amazing website called web.archive.org here you can track any website's past, provided it had automatically crawled(saved) that website in the past. or you can volunteer to do so by saving the website or webpage for future.
If you are a blogger or maintains a site, it proves as a useful tool too. they say they had saved 435 billion webpages. I found my blog there only saved 3 times.
