DoubleClick has confirmed that an Internet attack crippled its online advertising service Tuesday and caused a widespread outage among its customers.
The outage, first noticed at about 7 a.m. PDT, stemmed from a denial-of-service (DoS) attack that targeted DoubleClick's domain name server (DNS) system. The attack originated from "outside sources" that caused service disruption for DoubleClick's ad service clients, according to company spokeswoman Jennifer Blum.
"The vast majority is up and running," Blum said in an interview of the company's network of services that were affected by the attack. However, there are still some clients that are experiencing service outages. "We are working on it, and we have notified the proper people," Blum added. She declined to elaborate on which law enforcement bodies are involved in the investigation.
