Does your service gracefully degrade when a database, cache, or remote service becomes unavailable? Are you sure?

Graceful failure when downstream services are overloaded or down is critical to maintaining availability in complex systems, but because each of these failures is (hopefully!) rare, it can be hard to really trust that your systems will respond as expected in an emergency.

Come along to learn: how easy it is to mess this up (repeatedly), what it takes to maintain a trustworthy system, and a set of simple approaches for testing system failures in both CI and production.
