DoubleClick Inc. suffered a DDoS (distributed denial of service) attack Tuesday that knocked out its popular online ad-serving service and its own corporate Web site for several hours, the company has confirmed.
The DDoS attack targeted DoubleClick’s DNS (domain name system) and interrupted its ability to serve online ads to its 900 customers from about 10:30 a.m. EDT to 2 p.m. EDT, spokeswoman Jennifer Blum said. The DDoS attack also dinged performance on major Web sites that use DoubleClick-hosted ads. Web monitoring vendor Keynote Systems Inc. reported that availability dipped as low as 76.4 percent for the 40 major sites it tracks. “Beginning this morning, our DNS infrastructure [has] been under a denial-of-service attack from outside sources,” New York-based DoubleClick said in statement. “The attack caused severe service disruption for many of our ad-serving customers. The situation has been resolved.”
