Azure Firewall Policy during region failure

I have the below architecture in Azure -

138100-image.png

Two Virtual Network -- vnet1 (region: East US), vnet2 (region: West US)
Two Firewall -- fw1(on vnet1, East US) , fw2(on vnet2, West US)
One Firewall Policy in East US -- fwpolicy(attached to both fw1 and fw2)



Now my question is -

  1. If the East US region goes down, will the policy still be accessible by fw2(from West US) ?

  2. If yes then will there be any interruption on West US region's traffic because of the primary region failure ?
