Keys: probes in Santiago (SCL) · K-02

Runbook K-02 for Keys in Santiago (SCL). Marker xserv-k-f0f41d52b8e1. This page covers probes for LATAM operators, not a worldwide average.

Keys: How XServ runs it day to day

Probes for Keys (k-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.

Keys: What operators should measure

Policy for Keys is versioned as k-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.

Keys: Failure modes we actually see

Capacity notes for k-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.

Keys docs K-12

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

Keys design K-01

Design for Keys on letter K starts in São Paulo (GRU). Runbook k-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.
