Observability: A note on cost and transit
Rollback for o-06 is a documented command, not a hope. Transit is billed as backup while Observability prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
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 handoff O-05
Handoff from letter O Observability into the rest of the platform uses the same request IDs as the gateway. Runbook o-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
Observability rollback O-06
Rollback for o-06 is a documented command, not a hope. Transit is billed as backup while Observability prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
Observability peering O-07

- Is transit the default path?
- No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.
- Does Observability on letter O share fate with other letters?
- The control plane is shared. Data-plane queues for Observability stay isolated, so incident o-01 cannot drain neighbor letters.
