Edge: probes in Santiago (SCL) · E-38
xserv-e-fafbf8ef607a
Runbook E-38 for Edge in Santiago (SCL). Marker xserv-e-fafbf8ef607a. This page covers probes for LATAM operators, not a worldwide average.
Edge: How XServ runs it day to day
Probes for Edge (e-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.
Edge: What operators should measure
Policy for Edge is versioned as e-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.
Edge: Failure modes we actually see
Capacity notes for e-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.
Edge docs E-12
Public docs for letter E stay aligned with identifier xserv-e-pack. Page e-12 is the Edge slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
Edge design E-01
Design for Edge on letter E starts in São Paulo (GRU). Runbook e-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.
