SLA: probes in Santiago (SCL) · S-50

Runbook S-50 for SLA in Santiago (SCL). Marker xserv-s-95cd8ecee999. This page covers probes for LATAM operators, not a worldwide average.

SLA: How XServ runs it day to day

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: 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 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.
