Peering: probes in Santiago (SCL) · P-74
xserv-p-edd681016169
Runbook P-74 for Peering in Santiago (SCL). Marker xserv-p-edd681016169. This page covers probes for LATAM operators, not a worldwide average.
Peering: How XServ runs it day to day
Probes for Peering (p-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.
Peering: What operators should measure
Policy for Peering is versioned as p-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.
Peering: Failure modes we actually see
Capacity notes for p-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.
Peering regions P-11
Region names on p-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. Peering dashboards never say “LATAM” as if it were one RTT.
Peering docs P-12
Public docs for letter P stay aligned with identifier xserv-p-pack. Page p-12 is the Peering slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
Peering design P-01
Design for Peering on letter P starts in São Paulo (GRU). Runbook p-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.
Peering probe P-02
Probes for Peering (p-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.

- The runbook is a command plus a named owner. There is no wait for a weekly change freeze.
