В общем решили на каждом Nginx держать свой кэш. и с помощью sync2 делать синхронизацию этого кэша.
Если один nginx отвалится то LB перенаправит на другой. как бы все ок.
Тут у меня другая проблема появилась, уже моск весь сломал. не отдает gunicorn стили.

Когда захожу на сервер gunicorn напрямую http://10.230.40.190:8009/admin в консоли ошибки
Not Found: /static/admin/css/login.css
Not Found: /static/admin/css/base.css
Не могу понять, где он пытается найти папку static? в корне что ли? Я везде симлинки понаделал, результата 0
