QoS: handoff in São Paulo (GRU) · Q-53

xserv-q-0dd40118860b

Runbook Q-53 for QoS in São Paulo (GRU). Marker xserv-q-0dd40118860b. This page covers handoff for LATAM operators, not a worldwide average.

QoS: How this letter ties to the rest

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

QoS: A note on cost and transit

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

QoS: Why it matters on this continent

Design for QoS on letter Q starts in São Paulo (GRU). Runbook q-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.

QoS policy Q-03

Policy for QoS is versioned as q-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.

QoS capacity Q-04

Capacity notes for q-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.

QoS handoff Q-05

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

QoS rollback Q-06

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

Does QoS on letter Q share fate with other letters?
The control plane is shared. Data-plane queues for QoS stay isolated, so incident q-01 cannot drain neighbor letters.
Where is QoS measured first?
From Santiago (SCL) toward Bogotá. A global average is not an SLO for letter Q.
