An outage to popular Internet registrar GoDaddy.com that took thousands of websites offline for several hours Monday was the result of internal network events, not a malicious hacker, the company said on Tuesday.

The incident, which lasted from shortly after 10 a.m. PDT to 4 p.m. PDT, was due to a corruption of network router tables, said interim CEO Scott Wagner.

“We have determined the service outage was due to a series of internal network events that corrupted router data tables,” Wagner said in a company 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.”

“We take our business and our customers' businesses very seriously. We apologize to our customers for these events and thank them for their patience,” Wagner added.

An anonymous Twitter user calling himself “Anonymous Own3r” had claimed credit for the Monday attack, explaining in broken English filled with typos his justification for the attack.

"I'm taking godaddy down bacause well i'd like to test how the cyber security is safe and for more reasons that i can not talk now."

GoDaddy's version of the events makes sense, Anup Ghosh, chief scientist with security company Invincea, told FoxNews.com. Despite the resemblance to a so-called DDoS attack, the incident was never clearly a cyberattack save for the Twitter claims.

GoDaddy immediately acknowledged the incident on Monday, which took down the company’s own website and email services.

“We're aware of the trouble people are having with our site. We're working on it,” GoDaddy explained in a simple Tweet Monday afternoon. Within two hours, the company claimed to be making progress.

The incident was the second major event in the past two weeks that anonymous hackers have claimed credit for -- claims that have been refuted by authorities or involved parties. 

Last week unnamed hackers published a list of 1 million Apple iPad device IDs, claiming to have stolen the file from an FBI computer. Yesterday Paul DeHart, CEO of Blue Toad publishing company, revealed that software technicians within his company had confirmed the real source of the data: Blue Toad’s computers.
