According to Go Daddy, the outage was not caused by a denial of service attack nor any external influences. The company claims that a “series of internal network events that corrupted router data tables” are what’s to blame, not hackers. Once Go Daddy found the problem, they fixed it and set up measures to make sure that it doesn’t happen again.
Obviously, it wouldn’t look great if a service like Go Daddy suffered a DDoS attack. It would make people question the security and vulnerability of the service and their websites that are hosted through the service. I wouldn’t put it past a company to spin the truth to avoid some bad press. However, after yesterday’s confusion over Anonymous’s involvement and the user “Anonymous Own3r” stating he was acting on his own, I think it’s likely that the Go Daddy outage was internal and this supposed “hacker” was just seizing an opportunity to look powerful.
