+### Active-standby mode behavior
+
+In active-standby mode, during any planned maintenance or unplanned disruption affecting the active instance, the following behavior occurs:
 
 * **S2S and VNet-to-VNet**: The standby instance takes over automatically (failover), and resumes the site-to-site (S2S) VPN or VNet-to-VNet connections. This switch over causes a brief interruption. For planned maintenance, connectivity is restored quickly. For unplanned issues, the connection recovery is longer.
 * **P2S**: For point-to-site (P2S) VPN client connections to the gateway, P2S connections are disconnected. Users need to reconnect from the client machines.
 
 To avoid interruptions, create your gateway in **active-active** mode, or switch an active-standby gateway to active-active.

 You can configure an active-active gateway using the [Azure portal](tutorial-create-gateway-portal.md), PowerShell, or CLI. You can also change an active-standby gateway to active-active mode. For steps, see [Change a gateway to active-active](gateway-change-active-active.md).

 If you need to reset an active-active gateway, you can reset both instances using the portal. You can also use PowerShell or CLI to reset each gateway instance separately using instance VIPs. See [Reset a connection or a gateway](reset-gateway.md#ps).
