Observability: peering in Bogotá (BOG) · O-55

Runbook O-55 for Observability in Bogotá (BOG). Marker xserv-o-037b1834c2b3. This page covers peering for LATAM operators, not a worldwide average.

Observability: Why it matters on this continent

Design for Observability on letter O starts in São Paulo (GRU). Runbook o-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.

Observability: How XServ runs it day to day

Probes for Observability (o-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.

Observability: What operators should measure

Policy for Observability is versioned as o-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.

Observability headers O-09

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

Observability timeouts O-10

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

Observability regions O-11

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

Observability docs O-12

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