<p>I’m looking for ways to maintain high availability in the case that one of the policy pods is unavailable and found the following information on the official website:</p>

<p><a href="https://istio.io/docs/reference/config/policy-and-telemetry/istio.mixer.v1.config.client/#NetworkFailPolicy" rel="nofollow noreferrer">https://istio.io/docs/reference/config/policy-and-telemetry/istio.mixer.v1.config.client/#NetworkFailPolicy</a></p>

<p>But I did not find any additional information on how to apply these rules in my deployment. Can someone help me with this and tell me how to change these values?</p>

<p>This istio <a href="https://istio.io/blog/2017/0.1-using-network-policy/" rel="nofollow noreferrer">blog</a> about Using Network Policy with Istio redirects us to Calico documentation.</p>
<blockquote>
<p>Network Policy is universal, highly efficient, and isolated from the pods, making it ideal for applying policy in support of network security goals. Furthermore, having policy that operates at different layers of the network stack is a really good thing as it gives each layer specific context without commingling of state and allows separation of responsibility.</p>
