kworkbee opened a new issue, #2176:
URL: https://github.com/apache/apisix-ingress-controller/issues/2176
### Current Behavior
There is a problem with the unhealthy external service being delivered as it
is without being excluded from routing targets.
### Expected Behavior
Two external services (ALB configured in front of each) are configured as
upstream nodes and should be temporarily excluded from routing if a 5XX error
occurs through health check configuration.
### Error Logs
_No response_
