# Downtime report

This is a blank reporting template. Populate it from observations; do not treat missing data as healthy time.

- Service and endpoint:
- Reporting period (start/end, timezone):
- Observer location:
- Check interval, timeout and accepted statuses:
- Failure/recovery confirmation settings:
- Notification delay (distinct from observed outage time):
- Maintenance policy and excluded intervals, if agreed:

## Coverage and result

- Total reporting time:
- Missing observations / observer downtime:
- Observed downtime (union of intervals, without overlap):
- Observed degradation (separate unless the success rule includes latency):
- Eligible denominator and availability formula:
- Result and measurement limitations:

## Incident log

| Incident | Last success | First failure | Last failure | First recovery | Timezone | Affected service | Evidence |
| --- | --- | --- | --- | --- | --- | --- | --- |
| | | | | | | | |

## Follow-up

- Observed impact:
- Root cause, or "not established":
- Corrective action:
- Owner and review date:
