Backbone: peering in Bogotá (BOG) · B-55

Runbook B-55 for Backbone in Bogotá (BOG). Marker xserv-b-a5483a704866. This page covers peering for LATAM operators, not a worldwide average.

Backbone: Why it matters on this continent

Design for Backbone on letter B starts in São Paulo (GRU). Runbook b-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.

Backbone: How XServ runs it day to day

Probes for Backbone (b-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.

Backbone: What operators should measure

Policy for Backbone is versioned as b-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.

Backbone timeouts B-10

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

Backbone regions B-11

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

Backbone docs B-12

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

Backbone design B-01

Design for Backbone on letter B starts in São Paulo (GRU). Runbook b-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.
