 **Guidance**
 
-Having the ability to configure Site-to-Site VPN and ExpressRoute has several advantages. You can configure Site-to-Site VPN as a secure failover path for ExpressRoute, or use Site-to-Site VPNs to connect to sites that aren't connected through ExpressRoute
+By deploying active-active VPN concentrators on your premises, along with active-active Azure VPN Gateways, you can maximize resilience and availability by using a fully-meshed topology based on four IPSec tunnels.

 **Guidance**
 
-VPN Gateway uses service health alerts to notify about planned and unplanned maintenance.
+When using zone-redundant SKUs for VPN Gateways (VpnGw*AZ), make sure that you associate your gateway with zone-redundant Standard SKU public IP addresses. If a VPN gateway is associated with zonal Standard SKU public IP addresses, all the gateway instances are deployed in the same zone as the IP address(es). This recommendation applies to both active-passive gateways (which use a single public IP address) and active-active VPN gateways (which use two public IP addresses).
