Peering: A note on cost and transit

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

Peering: Why it matters on this continent

Design for Peering on letter P starts in São Paulo (GRU). Runbook p-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.

Peering: How XServ runs it day to day

Probes for Peering (p-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.

Peering policy P-03

Policy for Peering is versioned as p-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.

Peering capacity P-04

Capacity notes for p-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.

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