Partial degradation trigger threshold

The partial degradation trigger threshold refers to the difficulty in matching the clauses of a service contract or business interruption policy, historically built around the binary notion of total outage, to the reality of modern IT incidents, which most often show up as a performance degradation, abnormal latency or intermittent errors rather than a complete and clearly observable service stoppage. The difference is not merely semantic: a service that answers only one request in three, or answers correctly but ten times slower than usual, can interrupt a client's business just as much as a total outage without triggering a contract clause written around complete unavailability. For insurers and cloud providers alike, the challenge is to define a measurable, objective threshold, an error rate, response time or percentage of failed requests, precise enough to avoid disputes over what actually counts as a compensable outage. This gray zone structurally favors the provider or insurer, since the absence of a clear threshold shifts the burden of proving damage onto the client, who is often ill-equipped to demonstrate a diffuse degradation rather than a clean stoppage.
