cannot launch google.com

Hi,

The Safari on my Macbook Air just would not launch www.google.com, whether from 'Favourites' or manually typed in. It stalled while loading the page and finally showed as 'page not available'. I could easily access other sites secured or public just not Google.com. I started encountering this after I installed Flash update in July. I tried looking up at support but couldn't find any solution.

Has anyone encountered this? How can it be resolved?
