Microsoft has announced that Azure App Service supports VNet integration (for App Service outbound connections) and private endpoints (for App Service inbound inbound connections) at the Basic SKU. The App Service VNet integration feature enables App Service apps to access resources in or through a virtual network. For inbound access, private endpoints can be utilized, which allow clients located in a private network to securely access App Service apps over Private Link, which eliminates exposure from the public internet. For more details, see the VNet integration limitations.Sourcehttps://techcommunity.microsoft.com/t5/apps-on-azure-blog/generally-available-enhanced-network-security-features-for-app/ba-p/3285943 https://stefanos.cloud/blog/vnet-integration-and-private-endpoints-supported-by-app-service-basic-sku/

CaseWhen placing a Hyper-V cluster node in drain mode and then bringing the node back online (re-join), you may come across the following warning message: Cluster Shared Volumes root directory 'C:ClusterStorage' already exists. The directory 'C:ClusterStorage' was renamed to 'C:ClusterStorage.000'. Please verify that applications accessing data in this location have been updated as necessary.At the same time you observe that a temporary new folder C:ClusterStorage.000 has been created as shown below. You observe that the ClusterStorage.000 volumeThe above may occur on more than one Hyper-V hosts and may create outdated copies of more than one subfolders underneath the Cluster Shared Volume (CSV) volumes (cluster disks). For example for VM named VM001, you may have two copies of the "Virtual Machines" folder, one in C:ClusterStorage and one in C:ClusterStorage.000. You observe that the file copies under C:ClusterStorage.000 are outdated and that the syn...
