Zones: policy in Bogotá (BOG) · Z-27

Runbook Z-27 for Zones in Bogotá (BOG). Marker xserv-z-9454e2e6b00c. This page covers policy for LATAM operators, not a worldwide average.

Zones: What operators should measure

Policy for Zones is versioned as z-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.

Zones: Failure modes we actually see

Capacity notes for z-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.

Zones: How this letter ties to the rest

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

Zones rollback Z-06

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

Zones peering Z-07

Peering for Zones (z-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.

Zones cache Z-08

Cache rules for Zones on z-08 keep language-correct objects near Miami. São Paulo is a sibling cache, not an origin. TTLs are short enough that a bad asset does not live through a weekend.

Zones headers Z-09

Headers for z-09 carry the letter, the region (GRU) and a request id. Zones debugging in São Paulo should not require a packet capture in Santiago first.
