Конфигурация апстрима вот такая:

                server  1.2.3.6:80   weight=16000    max_fails=1000

                server  1.2.3.8:80   weight=16000    max_fails=1000

                server  1.2.3.4:80   backup;
                server  1.2.3.5:80   backup;
                server  1.2.3.6:80   backup;

                server  1.2.3.8:80   backup;
        }

Я   правильно   понимаю,   что  апстрим  знает  только  про  последний
запрошенный  бэкенд и может отправлять один запрос по кругу даже на те
бэкенды, которые ранее на него вернули ошибку?
