+Yes. When you create or delete a Route Server in a virtual network that contains a virtual network gateway (ExpressRoute or VPN), downtime is expected to last 10 minutes. It may take 30-60 minutes for the actual Route Server deployment to complete, and so we recommend scheduling a maintenance window of 60 minutes for deployment. If you have an ExpressRoute circuit connected to the virtual network where you're creating or deleting the Route Server, the downtime doesn't affect the ExpressRoute circuit's connections to other virtual networks.
