Markdown table
| Level | Impact | Response | Examples |
| --- | --- | --- | --- |
| SEV0 | Total outage. Core service is down for all users. | All hands. Incident commander paged. Status page updated within 15 min. | API fully down, data loss in progress, security breach |
| SEV1 | Major degradation. Many users blocked from core flows. | On-call plus secondary paged. Incident channel opened. Updates every 30 min. | Checkout failing for 50% of users, login outage in one region |
| SEV2 | Partial degradation. A feature is broken or slow. | On-call engages during business hours. Tracked to resolution. | Search results slow, exports failing, one non-core API erroring |
| SEV3 | Minor issue. Small user subset or cosmetic. | Ticket filed. Fixed in normal sprint work. | UI glitch, a single tenant misconfigured, stale cache |
| SEV4 | Negligible. Internal or informational only. | Backlog. No urgency. | Typo in an internal dashboard, noisy non-actionable alert |
