#3"The service outage was not caused by external influences. It was not a "hack" and it was not a denial of service attack."
So Anonymous0wn3r or whoever was just claiming responsibility for something they had no hand in? The router tables just corrupted themselves?

#4I don't know much about hardware at all, but aren't routers fairly simple, time tested pieces of hardware? Can they really corrupt en-masse in this way?

Routers can get quite complicated.
At a first level, routers will cache information about what machines are on which port of the router. This enables them to not forward a packet to every port on the router (reducing network load). This is normally done using MAC Addresses.
On more expensive routers, the router can understand IGMP, or multicast and route based on multicast joins. This enables an optimization on simple broadcasts because not every machine on the network needs to see these packets, but multiple machines might want to.

#6This doesn't do anything to explain why it was out for so long. I guess I should expect this type of thing from GoDaddy though, they are mainly a consumer company.

Yeah, with a name/handle like Anonymous0wn3r they sound very trustworthy. If they claimed they had a hand in something, it must be true.

#8"We have determined the service outage was due to a series of internal network events that corrupted router data tables."
I'm witholding any judgement on internal vs external involvement till this series of events is defined. (doubt it ever will be)

They're not that simple due to aggressive speed optimizations like caching frequently used routing information in hardware registers. If the cache gets corrupted due to electronic bogon flux, bad things happen. These events are rare (like once every billion operating hours) so you can imagine it's hard for the router vendors to find & fix them all.
It is a little sad that they didn't try rebooting the routers for so many hours.

#10Based 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.
