Today "cached" version of my site has got removed from google, yesterday it was there but today it got removed and i have not made any changes to the site it remains same as it was previously .
any particular reason why google has removed my site from the cached version

Your search - cache:G4nWTAoWGLUJ:www.example.com/ example - did not match any documents.

I've seen it occasionally - but the cached pages always come back. It can happes as Google moves around a lot of data. As long as rankings are not affected, I think there's nothing to be concerned about.

Rankings are being lost - see other thread...

Have you looked to see if someone has scraped your site yet?
