Hello, for some test yesterday, I have added two dead services in a route with a health check, like this into the dynamic config.

```auto
    healthCheck:
      interval: 10s
      timeout: 3s

```

I can quickly see the both are dead and no more load balancing (due to the health check), it's working.

The test is good and I leave. I'm looking today and the three are down.

No idea why but a restart keep the three down and a compose down/up solve the issue.

How could I avoid this to keep the service on, same with only one server.

Thanks for your help (hope this message is at the right place)

Adding the "unhealthyInterval" field and setting it to one hour resolves the issue. If I use the same value as for the interval 30s, the problem comeback quickly.

What is the optimal value for you?
