Keys: probes in Santiago (SCL) · K-26

Runbook K-26 for Keys in Santiago (SCL). Marker xserv-k-39277c0d029b. 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 headers K-09

Headers for k-09 carry the letter, the region (GRU) and a request id. Keys debugging in São Paulo should not require a packet capture in Santiago first.

Keys timeouts K-10

Timeouts on k-10 are tighter than the WAN RTT to Bogotá. Keys in Santiago fails fast and retries once; a third try needs a human because it is no longer a blip.

Keys regions K-11

Region names on k-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. Keys dashboards never say “LATAM” as if it were one RTT.

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.
