Container region evacuation
Test your containerized service's availability when an entire cloud region becomes unavailable. Verify that traffic automatically fails over to containers in backup regions without impacting the user experience.

How this Scenario works
This Scenario drops all network traffic to your containers in a specified cloud region, simulating a catastrophic regional outage. This forces your global load balancers and container orchestration to redirect all traffic to containers in your backup region(s).
Why run this Scenario?
Large-scale infrastructure outages are an unfortunate reality. Power outages happen, storms flood data centers, and curious sharks will snack on data cables. This Scenario tests your systems to see how they handle an entire cloud region suddenly becoming unavailable.
- Verify that your backup regions have sufficient container capacity and can scale to absorb the full production workload.
- Validate that global load balancers detect the regional outage and route traffic to container replicas in other regions.
- Test cross-region service discovery and container networking under failover conditions.
- Ensure that containerized services in backup regions handle the traffic surge without resource exhaustion.
What to expect when you run it
When a region becomes unavailable, traffic automatically fails over to containers in backup regions, and those regions handle the increased load without impacting the user experience.
