<p>In GKE every cluster has a single master endpoint, which is managed by Google Container Engine. Is this master node high available?</p>

<p>I deploy a beautiful cluster of redundant nodes with kubernetes but what happen if the master node goes down? How can i test this situation?</p>

<p>In Google Container Engine the master is managed for you and kept running by Google. According to the <a href="https://cloud.google.com/container-engine/sla" rel="nofollow">SLA for Google Container Engine</a> the master should be available at least 99.5% of the time. </p>
