You are managing a globally accessible website with a frontend web service and a backend database service hosted on separate clusters across four different Google Cloud Platform regions. Cloud Load Balancing is utilized to direct user traffic to the nearest region. During the application of a critical security patch to the backend database, a configuration error in Region 3 causes 50% of user requests to time out. The other regions are scaled to handle the total user traffic. What is the best action to mitigate the impact of the unsuccessful patching on users?
A
Increase the frontend capacity in Region 3 to handle the failing requests.
B
Redirect new requests from Region 3 to other regions and drain the existing ones.
C
Restore the Region 3 backend database from a backup and restart it.
D
Roll back the patch in Region 3 and operate the database without it.
