Routing: capacity in Miami (MIA) · R-64

Runbook R-64 for Routing in Miami (MIA). Marker xserv-r-0921b22274bf. This page covers capacity for LATAM operators, not a worldwide average.

Routing: Failure modes we actually see

Capacity notes for r-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.

Routing: How this letter ties to the rest

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

Routing: A note on cost and transit

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

Routing docs R-12

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

Routing design R-01

Design for Routing on letter R starts in São Paulo (GRU). Runbook r-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.

Routing probe R-02

Probes for Routing (r-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.

Routing policy R-03

Policy for Routing is versioned as r-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.
