Failover: peering in Bogotá (BOG) · F-07

Runbook F-07 for Failover in Bogotá (BOG). Marker xserv-f-7db188705607. This page covers peering for LATAM operators, not a worldwide average.

Failover: Why it matters on this continent

Design for Failover on letter F starts in São Paulo (GRU). Runbook f-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.

Failover: How XServ runs it day to day

Probes for Failover (f-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.

Failover: What operators should measure

Policy for Failover is versioned as f-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.

Failover capacity F-04

Capacity notes for f-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.

Failover handoff F-05

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

Failover rollback F-06

Rollback for f-06 is a documented command, not a hope. Transit is billed as backup while Failover prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.

Failover peering F-07

Peering for Failover (f-07) prefers the IX fabric that already carries last-mile ISPs in Bogotá. Session counts and prefix limits are on the same page as the Miami backup path.
