Backbone: handoff in São Paulo (GRU) · B-05

Runbook B-05 for Backbone in São Paulo (GRU). Marker xserv-b-88d1ad083800. This page covers handoff for LATAM operators, not a worldwide average.

Backbone: How this letter ties to the rest

Handoff from letter B Backbone into the rest of the platform uses the same request IDs as the gateway. Runbook b-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.

Backbone: A note on cost and transit

Rollback for b-06 is a documented command, not a hope. Transit is billed as backup while Backbone prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.

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 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 probe B-02

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.
