         What do you do when a service you depend on stops responding? Circuit breakers enable you to bypass a failing service, allowing it time to recover, and preventing your users from seeing nasty error messages.
         Steeltoe includes a .NET implementation of Netflix Hystrix, a proven circuit breaker implementation with rich metrics and monitoring features.
