How this was decided

Not an editorial call. The URL on file failed three consecutive checks, with a confirmation re-probe before the streak counted (a bot-wall response never counts as one), and the 3-miss rule marks the listing discontinued automatically. If the URL responds again, the registry restores it on its own: warn first, then active. Both directions are recorded as events.
