Actually, you can't really say that. It's true that it was a simple
power outage for Amazon.
Power failed, causing the AWS service at certain locations to experience issues.
Any of the issues related to services at locations that didn't lose
power are a possible result of cascade.
But as for the other possible outages being reported... Instagram,
Pinterest, Netflix, Heroku, Woot, Pocket, zoneedit.
Possibly Amazon's power failure caused AWS problems, which resulted in
issues with these services.
Some of these services may actually have had redundancy in place,
but experience a failure of their service as a result of unexpected
cascade from the affected site.
