SLA: headers in São Paulo (GRU) · S-09

xserv-s-03456a0017df

Runbook S-09 for SLA in São Paulo (GRU). Marker xserv-s-03456a0017df. This page covers headers for LATAM operators, not a worldwide average.

SLA: What operators should measure

Policy for SLA is versioned as s-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.

SLA: Failure modes we actually see

Capacity notes for s-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.

SLA: How this letter ties to the rest

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

SLA capacity S-04

SLA handoff S-05

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

SLA rollback S-06

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

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