Cómo medimos el uptime
3 fuentes cruzadas (UptimeRobot · Sentry · Cloudflare Analytics) · external-first ground truth · conservative reporting · 5 inclusions + 5 exclusions explícitos · 6 policies + right to dispute Enterprise.
3 fuentes cruzadas
Polling 60s contra 5 endpoints health (worker · landing · dashboard · status · webhook). Headquartered fuera nuestro infra · honesty enforced by external party.
Captures exceptions runtime · 5xx responses · timeout failures. Detecta degradation antes que UptimeRobot (errores antes de full outage).
Aggregated request counts · 4xx/5xx ratios · CPU time · cold start frequency. Internal · highest granularity.
3 fórmulas matemáticas
Period typically calendar month. Downtime cuenta desde 2 polls UptimeRobot consecutivos rojos hasta 2 polls consecutivos verdes (evita falsos positivos).
Detection timestamp = first alert sent (Sentry email/SMS o UptimeRobot polling). Incident start = earliest log entry indicating issue.
Resolution timestamp = service fully restored (health checks verde 2 polls consecutivos + 0 nuevos errors Sentry 5min). Includes humano reaction + diagnosis + fix + deploy + verification.
- ·Unplanned outages (cualquier failure no anunciado)
- ·Degraded performance (response time >5x baseline)
- ·Cualquier 5xx response a webhook crítico (Meta · Cal · Stripe)
- ·Loss of data integrity (RLS violation · cross-tenant leak · data corruption)
- ·Complete service unavailability cualquier subsystem (worker · DB · queue · cache)
- ·Mantenimiento programado anunciado >72h antes (ventanas típicas 03:00 UTC sábados)
- ·Failure causa fuerza mayor documentada (Cloudflare regional outage · Supabase EU outage)
- ·Failure causado por cliente (e.g., revocó OAuth · borró tenant manualmente)
- ·Trial accounts (best-effort · no SLA contractual)
- ·Issues isolados a 1 cliente single (não systemic · reported individually)
