+# Circuit Breaker 2
+
+### Advanced circuit breaker
+The advanced circuit breaker breaks the circuit if a if a threshold of failures is reached within a specified time period and with a minimum number of requests reached in that time period. 
+
+In this example the circuit breaks when there are 50% failures, in a 3 second sampling window, with a minimum throughput of 6 request in the 3 second window; if the circuit breaks it will be open for 5 seconds. When the circuit breaker is open no traffic will cross it, instead a `BrokenCircuitException` will be thrown.

+There are times when no number of retires will solve a problem, the underlying service just won't respond. In this case the Fallback policy is you last resort. It can page an admin, scale a service or return a default.

+### Retrying When an Exception Occurs
+The Polly NuGet package has been added and we are going to use the Retry Policy when querying database. 
+The policy states that if an exception occurs, it will retry up to three times.
+
+Note how you execute the unreliable code inside the policy. `retryPolicy.Execute(() => errorProneCode.QueryTheDatabase());`
