Go Daddy acknowledged that its site was down via its company Twitter account.
"Status Alert: Hey, all. We're aware of the trouble people are having with our site. We're working on it," the company tweeted.
Go Daddy later signaled that it was being flooded with messages from concerned customers by tweeting: "So many messages, can't get to you all... Sorry to hear all your frustration. We're working feverishly to resolve as soon as possible."
Several business owners that use Go Daddy's hosting service took to Twitter to ask "Anonymous Own3r" why they were hurting other innocent companies when the attack was ultimately aimed at Go Daddy.
When responding to a question from a Mashable reporter, the user tweeted: "I'm taking godaddy down bacause [sic] well i'd like to test how the cyber security is safe and for more reasons that i can not talk now."
Earlier this year several Internet activists rallied on Reddit and launched a boycott against Go Daddy for its support of the Stop Online Piracy Act and Protect IP Act. They threatened to move their domain names en masse to another registrar. Go Daddy later reversed its support for the anti-piracy bills.
