Popular web hosting company GoDaddy said in a late Monday statement that service to most of the affected customers of a major outage of countless GoDaddy websites - following an Anonymous attack - had been restored.

Earlier, claiming the credit for the intermittent service outage witnessed by GoDaddy on Monday, a hacker - using Twitter handle "Anonymous Own3r", and describing himself as the "security leader of #Anonymous" - said that he was solely responsible for the attack; and that it was not a coordinated effort carried out by entire Anonymous hacking group.

About the attack, a GoDaddy spokesperson told PCWorld that websites serviced by the domain registrar went down at around 1:25 p. m.; and added that, by about 5:40 p. m., the services had been restored "for the bulk of affected customers."

Later, at around 8:30 p. m. ET, GoDaddy reiterated in a statement on its official Twitter account that most customer hosted sites were "back online." The company also said that it was "working out the last few kinks" for its site and control centers; and added that no customer data had been compromised in the Anonymous attack.

Assuring the GoDaddy customers that the service outage was isolated to just a denial-of-service attack, GoDaddy spokeswoman Elizabeth Driscoll told CNET that "at no time was sensitive customer information, such as credit card data, passwords, names, addresses, ever compromised."
