xserv-s-919878f02eea

Runbook S-77 for SLA in São Paulo (GRU). Marker xserv-s-919878f02eea. This page covers handoff for LATAM operators, not a worldwide average.

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: A note on cost and transit

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.

SLA: Why it matters on this continent

Design for SLA on letter S starts in São Paulo (GRU). Runbook s-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.

SLA docs S-12

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

SLA design S-01

Design for SLA on letter S starts in São Paulo (GRU). Runbook s-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.

SLA probe S-02

Probes for SLA (s-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.

SLA policy S-03

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.

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.
