  company's domain name servers (DNS) -- machines that help direct
  Internet traffic -- causing "severe service disruptions" for all 900 of
  its customers. Blum said the outage was caused by a distributed

  thousands of hijacked computers to flood a Web site with so many bogus
  Web page requests that it renders the site unavailable to legitimate
  users.

  The FBI is not investigating the incident because DoubleClick has not
  filed a report, said bureau spokeswoman Megan Baroska.
