Ask HN: Simulating an Availability Zone Outage in AWS

I'm looking to simulate a full outage of an Availability Zone in AWS and wondering if anyone has a suggestion on the best way to do this.

Netflix has a tool called Chaos Gorilla that sounds perfect, but they never released it (only the Monkeys).

The other option I thought might work would be to adjust the routing table, so that all of the subnets in the target AZ are black holed. Any other suggestions?
