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.
