The original silences expired on 2026-08-04, so TargetDown had been firing every
4h for eleven days — noise that dulls the very alert path the backup work in
#0030 depends on. New silence is scoped to the two GAME jobs rather than the
alertname alone, so future TargetDowns for anything else still get through, and
it carries an expiry that forces a re-decision if the vSwitch move has not
happened by then. The date is now this issue's de facto deadline, so it also
went into the wartegrund where STATUS surfaces it.
