Ask HN: Simulating an Availability Zone Outage in AWS

4 points by abrookewood ↗ HN
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?

My AWS representative just suggested removing the security groups from different layers of the stack as this results in almost immediate loss of network connectivity. It's also inherently scriptable, so it looks like a good option.
