Google translate:

This exercise is held irregularly during the birth festival.
Please participate, please inform the receptionist during the implementation period

"Shinsei Festival military exercises" can only enter during a certain period during the seasonal event.

In "Shinsei Festival Military Exercise", you can enter by talking to "Information desk for urban exercises" that appears only during the period when it can enter.

Notes:
While it does say "irregular" and "certain period", that isn't necessarily the same as "random". It could be, so maybe the FR version is correct, but it could also mean that it works only during certain irregular preset times.

One of the JP forum threads states that JP players are guessing the event will be available during the 14 hour broadcast. Not sure where they got that idea, but I suppose that's just as possible as any other player guess here.

Based on what I’m translating, I think the “exercises” the description is referring to are the FATEs that will be present in the instance, in which the “carried out irregularly” would make sense (since FATEs spawn randomly).

The second line, I’m translating「「新生祭軍事演習」は、シーズナルイベント開催中の特定期間にかぎり」as “The ‘Rebirth Festival Military Exercises’ will be restricted to the seasonal event in-progress designated period”, and then the 「突入することができます」phrase is just saying “can embark on [these exercises]”. So I’m still not necessarily picking up on anything that insinuates randomness (in terms of the instance itself being random). I think this has to be a bug; if not, then they REALLY screwed up when they were translating the English text.

I don’t know. If they were going to implement a random instance feature (or delay it until the 14-hour broadcast/tomorrow in all time zones/whatever), it would have been best to just put it out on the event webpage or launch the event at that time lol. Though, as I said before, that kind of design would be a bit dumb: not everyone has time to idle by the vendors waiting for the Recruiter NPC to spawn whenever he pleases. /shrug

They probably took it down to change the reward, from the white raven earrings to replica ones or something else.

Doubtful. You can view the earrings at the Rising Attendant under the rewards. Both the White Ravens and the Manderville Earrings are 50 Rising Tokens each.

Is it in all city-states or just ul dah?

The English text says you can find Rising Recruiters in any of the three city-states.
