Based on a long history of working in datacenters I'd bet someone misconfigured something and later claimed it was "corrupted" to save their ass - happens all the time. It's just so simple to make very confusing and damaging mistakes in a complicated network. I wouldn't be surprised to hear that GoDaddy's corporate culture wouldn't respond well to someone admitting to a mistake this damaging.
Everyone there is on pins and needles at this point. Since Silverlake's investment in the company, many hatchets have dropped on jobs, and it's really the only decent tech firm in Phoenix to work at.
My guess is that there is some hiney covering going on with this explanation, and the interim CEO has little cause to care too much about responsibility, since he'll likely be out before year's end anyway.
I really feel for the folks who work there. Many, many talented people who don't have an inch to make a mistake. When I was last there, they had just released an internal communication about the new company motto: "It won't fail because of me." Horrible, horrible, backward-ass culture.
