The error_page in question does internal redirect to 
"/maintanance.html", which in turn returns 503 due to "return 503" 
at sever level.

I.e. there is no way to reach /maintanance.html, and hence nginx 
returns builtin page.

Using "return 503" at location level will work, assuming you'll 
define special location for /maintenance.html without the return. 
i.e.:

    location / {
        error_page 503 /maintenance.html;
        return 503;
    }

    location /maintanance.html {
        # no "return 503" here
    }

This works as named location's doesn't re-execute server level 
rewrite directives (i.e. no "return 503" here as well).
