</div>Then a condition must occur where host A fails right after processing the<br>
request, they usually fail before accepting a request, it also depends on<br>
the timeout for a request. And it also depends what nginx considers a fail,<br>
nginx might not fail a host when it does not return from accepting a<br>
request.<br>
<br>
You will have to simulate this to find out the conditions for a fail.<br>
