GoDaddy.com, the domain site that claims to manage 53 million names, has restored most service was the victim of a cyberattack Monday by hackers including Anonymous, the company announced.

"We're working out the last kinks for our site and control centers," the private Scottsdale, Ariz., company's representatives advised via Twitter. "No customer data compromised."

GoDaddy's company's own site worked throughout the denial-of-service (DNS) attack Monday but sites it operates on behalf of customers were blocked in late afternoon. GoDaddy has eight large server farms in the U.S. as well as one in India.

Some of its server traffic was been transferred to VeriSign Inc. (Nasdaq: VRSN), the Reston, Va., provider of Internet services, GoDaddy advised.

The company tweeted it was "aware of the trouble people are having with our site" and urged customers to monitor Twitter for more information.

Aon Monday, an apparent attacker with the tag AnonymousOwn3r claimed the attack would test how the cyber security is safe and for more reasons than I can not talk now."

In last winter's controversy concerning the proposed Stop Online Piracy Act (SOPA) in the U.S. Congress, GoDaddy was targeted because it supported the law, which was championed by publishers and Hollywood studios. The law was never brought up for a vote in either house.

GoDaddy was previously subject to DNS attacks in 2007 and 2009.
