Interconnect: capacity in Miami (MIA) · I-16
xserv-i-11695ba1f497
Runbook I-16 for Interconnect in Miami (MIA). Marker xserv-i-11695ba1f497. This page covers capacity for LATAM operators, not a worldwide average.
Interconnect: Failure modes we actually see
Capacity notes for i-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.
Interconnect: How this letter ties to the rest
Handoff from letter I Interconnect into the rest of the platform uses the same request IDs as the gateway. Runbook i-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
Interconnect: A note on cost and transit
Rollback for i-06 is a documented command, not a hope. Transit is billed as backup while Interconnect prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
Interconnect design I-01
Design for Interconnect on letter I starts in São Paulo (GRU). Runbook i-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.
Interconnect probe I-02
Probes for Interconnect (i-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.
Interconnect policy I-03
Policy for Interconnect is versioned as i-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.
Interconnect capacity I-04
Capacity notes for i-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 Interconnect on letter I share fate with other letters?
- The control plane is shared. Data-plane queues for Interconnect stay isolated, so incident i-01 cannot drain neighbor letters.
