Routing: cache in Miami (MIA) · R-68

Runbook R-68 for Routing in Miami (MIA). Marker xserv-r-35a4b585e292. This page covers cache for LATAM operators, not a worldwide average.

Routing: How XServ runs it day to day

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: What operators should measure

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.

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 handoff R-05

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 rollback R-06

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.
