Jonathan-

	Yeah we are triggering a maintenance page via the existance of a  
file. Here is how it looks in the config file.

# Rewrite all the requests to the maintenance.html page if it exists.
if (-f $document_root/system/maintenance.html) {
   return 503;
}


error_page 503 @503;
location @503 {
   rewrite  ^(.*)$  /system/maintenance.html break;
}


	This means that if $document_root/system/maintenance.html exists,  
then only serve that file and nothing else for every request.
