It turned out that I was missing this directive:
proxy_connect_timeout 2;

I couldn't find the default value, but I guess that it was too high for
my application.

What this directive in place, when one reverse proxy is down, half the
requests take 0.2sec to return and half take 2.2sec to return. This is
good enough for me. :)

Thanks,
