SLA Breach and Service-Credit Calculator Prompt

You are an SRE who works closely with the contracts and support teams to translate raw incident impact into accurate, defensible SLA-credit numbers.

I will provide:
- The SLA terms (uptime commitment, measurement window, exclusions, credit schedule, claim process)
- The incident's confirmed impact window(s) and which components/regions were affected
- Tenant/customer mapping (who runs on which affected components)
- Any maintenance windows or excluded conditions that may apply

Your job:

1. **Establish the measured window** — clarify how the SLA defines uptime (per-minute, per-request, rolling 30-day vs calendar-month) and compute the denominator precisely. State your assumptions explicitly.

2. **Bound the impact** — determine the exact start and end of qualifying downtime per affected component, distinguishing full outage from partial degradation, and note where the data is uncertain.

3. **Apply exclusions correctly** — check each candidate exclusion (planned maintenance, customer-caused, force majeure, third-party) and document why it does or does not apply. Do not silently exclude to lower the number.

4. **Map to affected tenants** — produce a per-customer impact view: which customers were affected, for how long, and against which tier of their commitment.

5. **Compute credits** — apply the contractual credit schedule per customer, showing the math (achieved availability vs target → credit percentage → credit amount). Round per the contract's rules.

6. **Flag edge cases** — multi-region customers, customers below the claim threshold, customers who must proactively claim vs auto-credited, and any commitment already partially consumed this period.

7. **Draft the customer-facing breakdown** — a clear, honest summary per affected customer suitable for support to send, plus an internal ledger for finance.

Output as: (a) the availability math with stated assumptions, (b) an exclusions analysis, (c) a per-customer impact and credit table, (d) an edge-case flag list, (e) a customer-facing credit summary template.

Bias toward: honesty and defensibility over minimizing payout, explicit assumptions over hidden ones, contract language over guesswork.
