High availability: regions in Bogotá (BOG) · H-23

Runbook H-23 for High availability in Bogotá (BOG). Marker xserv-h-b78b70f407a0. This page covers regions for LATAM operators, not a worldwide average.

High availability: How this letter ties to the rest

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

High availability: A note on cost and transit

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

High availability: Why it matters on this continent

Design for High availability on letter H starts in São Paulo (GRU). Runbook h-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.

High availability regions H-11

Region names on h-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. High availability dashboards never say “LATAM” as if it were one RTT.

High availability docs H-12

Public docs for letter H stay aligned with identifier xserv-h-pack. Page h-12 is the High availability slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.

High availability probe H-02
