Uptime: policy in Bogotá (BOG) · U-63

Runbook U-63 for Uptime in Bogotá (BOG). Marker xserv-u-e799e0cbb099. This page covers policy for LATAM operators, not a worldwide average.

Uptime: What operators should measure

Policy for Uptime is versioned as u-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.

Uptime: Failure modes we actually see

Capacity notes for u-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.

Uptime: How this letter ties to the rest

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

Uptime probe U-02

Probes for Uptime (u-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.
