kitten3 doesn't have a DirPort configured. Relays need a DirPort to be a fallback directory mirror. Let me know if you are able to configure a DirPort for it.
Also let me know if you want to opt-in or opt-out other relays in that family.
Thanks for the report, corrected !
For others nodes of my family, avoid kitten5 and 6 at this moment, potential migration with IP change in few months.
