 It isn't common to have multiple ISPs to connect to. If the slowdown is on a specific network and other options were explored, then you might want to contact your ISP to see if they have any limiters on RDP/SSH connections.

 - Shutdown virtual machines when users don't connect: If students don't connect to the virtual machine after some time and if the duration is too short, the virtual machine will be shutdown. The timing can affect students starting the virtual machine themselves, or if schedules are used in the lab. Changing the idle setting to a longer duration is an option but has potential cost implications. If schedules are being used, the virtual machines can be started closer to when the class time starts.

 The [activity log](/azure/azure-monitor/essentials/activity-log?tabs=powershell) can be filtered on the resource group that the lab is located in. The events can take a few minutes to be available in the log. These event logs contain more detailed information that can be used for troubleshooting and should be included if a support ticket needs to be created.

 #### Missing a Network Security Group 
 For a lab plan configured with advanced networking, one of the first checks is to confirm that the lab services network subnet has a network security group connected to it. This lets the RDP/SSH connections be allowed through. Without a network security group, all connections are blocked to the virtual machines (template VM and student VMs).
