DirPortFrontPage gives 503 on loaded dirmirror
When configuring DirPortFrontPage, a loaded mirror will return a 503 consistently when the DirPort is hit. A browser will simply display a white page and not indicate the error condition at all, so the output can be surprising to the average user. If we cannot "fix" this, at least warning the user is probably a sane idea.
