A WebmasterWorld thread named News.Google.com problems? documented how when you did a search, for example on Reuters and then repeated the search over and over again, the number of stories, in a matter of a refresh, would jump from "26,900 to 13,500 to 0." Now I am trying this now, and I can not reproduce the issue. But others checked about 5pm (EST) yesterday, and have noticed the same issue. Maybe it has been fully resolved.

Couldn't this simply be Google denying an IP results due to hammering? If I had a user refresh a page over and over and over again you'll be sure he gets booted. News doesn't update that fast so there is no reason ti refresh so much. -PK
