Gateway: headers in São Paulo (GRU) · G-33

Runbook G-33 for Gateway in São Paulo (GRU). Marker xserv-g-0c45c44e2987. This page covers headers for LATAM operators, not a worldwide average.

Gateway: What operators should measure

Policy for Gateway is versioned as g-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.

Gateway: Failure modes we actually see

Capacity notes for g-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.

Gateway: How this letter ties to the rest

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

Gateway rollback G-06

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