An organization experiences a partial failure in one group of servers hosting a front-end service. The rest of the infrastructure remains reachable. Logs reveal connectivity rejections for a subset of users. Which approach isolates the malfunction with minimal user impact?
Deactivate logging and rotate keys across servers
Investigate a gateway rule in the malfunctioning group
Expand CPU capacity for primary compute instances
Deploy new application versions across the environment
When a localized disruption occurs, investigating the network rules or firewall settings in the malfunctioning group is the best approach for restoring availability to affected users. Reconfiguring resources across the environment or rotating keys across servers introduces extra adjustments that do not directly address the core connectivity error. Increasing CPU capacity in unaffected instances does not fix the rejection issue affecting only a portion of the service.
