Domain registrar and Web hosting company Go Daddy said that yesterday's outage, which brought down an untold number of Web sites, was not the result of a hacker attack.

"The service outage was not caused by external influences," the company's interim CEO, Scott Wagner, said in a statement. "It was not a 'hack' and it was not a denial of service attack (DDoS)."
