Observability: policy in Bogotá (BOG) · O-03

Runbook O-03 for Observability in Bogotá (BOG). Marker xserv-o-416465df955f. This page covers policy for LATAM operators, not a worldwide average.

Observability: What operators should measure

Policy for Observability is versioned as o-03. Operators measure error rate, p95 from Bogotá, and time-to-rollback — not a worldwide average. Changes land in Bogotá first, then Miami, with a hold if either region regresses.

Observability: Failure modes we actually see

Capacity notes for o-04 assume rainy-season power in Miami and festival peaks toward São Paulo. The failure we actually see is a single uplink, not a cartoon partition of the whole continent. Spare ports and a second provider sit on the same runbook.

Observability: How this letter ties to the rest

Handoff from letter O Observability into the rest of the platform uses the same request IDs as the gateway. Runbook o-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.

Observability design O-01

Design for Observability on letter O starts in São Paulo (GRU). Runbook o-01 keeps a single owner, a written rollback, and a traffic split that can be reversed without a global freeze. Neighbors in Santiago only take overflow after the local pool fails a health window.

Observability probe O-02

Probes for Observability (o-02) leave Santiago every 15s toward Bogotá. XServ pages the named owner if loss or RTT crosses the letter budget. A probe never shares a queue with bulk transfers, so a saturated WAN does not hide a dead PoP.
