At 5 pm today searches via google.cn (which currently redirects to google.hk) and google.com started to intermittently trigger connection resets after searches were attempted. Within a couple hours any & all searches would trigger a connection reset (i.e. you would get an error message page instead of the expected search results). It seems that occasionally I am able to still get a search result in different ways (via Firefox search tool bar, etc), but looks like a message is being sent loud and clear to Google HQ.
