Today every down event opens a ticket. The same tickets, replayed with a minimum outage length before one opens.
Overlapping device outages at a store merge into one episode; the longest is compared with the threshold. Tickets a person reported always open. Comments avoided is an upper bound.
Outage length barely predicts whether a human was needed: 31% of self-healed agent-worked tickets had a longest outage under 15 minutes, and 19% of fix tickets never had one over 15 minutes.
