GoDaddy says it's working aggressively to restore all services GoDaddy, which hosts more than 5 million websites, said it was still investigating what may have caused many of its clients' sites to get knocked offline. The Scottsdale, Ariz.-based Internet company told the Los Angeles Times that its IT department was working aggressively to investigate the problem as well as restore its clients' websites. It declined to say how many websites were affected. "GoDaddy did experience some intermittent outages, and it impacted our site and some customer sites," company spokeswoman Elizabeth Driscoll said. We're working to restore all services. Some are already back online. Driscoll said the outages began shortly after 10 a.m. PDT, and they may have caused millions of websites to go offline. But the problem may be bigger. Some customers who don't host with GoDaddy but did register their Internet domain names with the company have also said they've experienced issues including users not being directed to their desired websites. GoDaddy said it has registered more than 53 million domain names. "My sites are down, but so are millions of struggling small biz owners," said a user named Darnell Clayton on Twitter, who also said he registered his domain with the company but doesn't use GoDaddy for hosting. The hacker group Anonymous has taken responsibility for taking the websites down but GoDaddy's Driscoll said she could not confirm the claim. Multiple members of Anonymous have said they were behind the attack, but none of those claims has been verified. It also is unclear what kind of hack or attack led to the massive problem although that hasn't stopped many on the Web from speculating. GoDaddy said users can follow it on Twitter or its website for more updates as they come.
