+= Minimum bandwidth
+
+During cluster deployment, {product-title} requires a minimum bandwidth of {mos-min-bandwidth} between cluster resources and public internet resources. When network connectivity is slower than {mos-min-bandwidth} (for example, when connecting through a proxy) the cluster installation process times out and deployment fails.
+
+After deployment, network requirements are determined by your workload. However, a minimum bandwidth of {mos-min-bandwidth} helps to ensure timely cluster and operator upgrades.
