Web hosting firm and domain registrar Go Daddy said a distributed denial-of-service attack was not to blame for Monday's mass outage affecting potentially millions of sites, but instead technical malfunctions internal to its operations.

"We have determined that the service outage was due to a series of internal network events that corrupted our router data tables," the company's interim CEO, Scott Wagner, said in a statement. "Once the issues were identified, we took corrective actions to restore services for our customers and GoDaddy.com. We have implemented measures to prevent this from occurring again."

The company said no customer data was compromised in the outage, which lasted much of the day for some sites.

A purported member of Anonymous, using the handle @AnonymousOwn3r, had taken credit for the takedown. The person stood by their word Tuesday, despite Go Daddy's statement.

A spokeswoman did not immediately respond to a request for comment.
