Azure Front Door configurations:
- one backend pool;
- two backends (both are azure app service) in the pool;
- Probe interval: 30 seconds
- Load balancing: Sample size - 2; Successful samples required: 1; Latency sensitivity: 0
- one of backend is stopped;
Issue:
when accessing the front-door (my-afd-url.azurefd.net), it returns 403 occasionally. from my understanding, if any backend is unhealthy , front-door should always direct requests to the healthy one.
it seems failover not working for me. does the probe/load-balancing configuration matter here? please help.
