Thank you for your post!
When it comes to your Key Vaults availability and redundancy, based off your current Vault regions (East / West US), you should already be set-up for automatic failover across regions since East US is paired with West US to support cross-region replication based on proximity and other factors. For more info.
In the regions that don't support automatic replication to a secondary region, you must plan for the recovery of your Azure key vaults in a region failure scenario. To back up and restore your Azure key vault to a region of your choice, complete the steps that are detailed in Azure Key Vault backup.
