XEP-0310: Presence State Annotations <https://xmpp.org/extensions/xep-0310.html> feels like prior art for this kind of problem?
I scrolled quickly over that XEP: - it doesn't seem like it'd provide an update when the service is _back_ - it seems aimed at reporting that a fulljid and possibly barejid are unavailable, rather than a service itself But per my other email I'd expect presences to serve that purpose (like they seem to in XEP-0310) - except a client would need to indicate interest in receiving it without confusing the user with roster spam.
