Zones: timeouts in Santiago (SCL) · Z-70

Runbook Z-70 for Zones in Santiago (SCL). Marker xserv-z-fceea556519c. This page covers timeouts for LATAM operators, not a worldwide average.

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: A note on cost and transit

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 docs Z-12

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

Zones design Z-01

Design for Zones on letter Z starts in São Paulo (GRU). Runbook z-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.

Zones probe Z-02

Probes for Zones (z-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.

Zones policy Z-03

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.
