Google concerned about robots

NEW YORK -- The popular search engine Google cut off access to dozens of innocent Comcast subscribers earlier this month out of frustration with performance-draining automated search robots.

Comcast officials say fewer than a hundred subscribers were affected, and full access was restored within a few hours.

Nevertheless, the incident highlights Google's growing concerns over automated requests and the lack of precise response tools in its arsenal.

Google bans the use of software robots that automatically retrieve information from its search engines.

The company believes such requests can tax its resources and can slow Google's performance.
