I am really surprised they don't have a high availability setup for their database, etc being a fortune 500 company. Hours of downtime is serious money for them it would seem. Well if they did have such setup, it failed.
Even a bootstrapped startup could get a MongoDB Cluster or something similar going in multiple datacenters.
The power company Tweeted about it also. https://twitter.com/GeorgiaPower/status/762662968572215296
So I guess it was a power outage only at their place...
But the whole idea of not having working redundancy in a multibillion dollar business really makes me question their story.
So not to sound like a conspiracy theorist, but I do think there is a possibility they got hacked. And if that hunch is true then calling it a power outage instead of admitting it is a insult to our intelligence.
