Thank you for reaching out.
I understand you wish to know if you can set-up Azure VPN Gateway to failover to secondary region in case if the primary region goes down.
- Deploy a Zone redundant VPN Gateway for Zone level failures:
You can deploy zone-redundant virtual network gateway in Azure availability zones. This brings resiliency, scalability, and higher availability to virtual network gateways. Deploying gateways in Azure availability zones physically and logically separates gateways within a region, while protecting your on-premises network connectivity to Azure from zone-level failures.
More details regarding the zone redundant VPN Gateway can be found here.
Many Azure regions provide availability zones, which are separated groups of datacenters within a region. Availability zones are close enough to have low-latency connections to other availability zones. They're connected by a high-performance network with a round-trip latency of less than 2ms. However, availability zones are far enough apart to reduce the likelihood that more than one will be affected by local outages or weather.
- For region wide failover:
There is no out of the box solution for this but you can go through this Azure disaster recovery document here but it requires a configuration of a new VPN Gateway in a different Azure Region and during disaster recovery you will have to set-up P2S the connection for this new region.
Hope this helps! Please let me know if you have any additional questions or concerns. Thank you!
