Peering: cache in Miami (MIA) · P-20

Runbook P-20 for Peering in Miami (MIA). Marker xserv-p-206975198192. This page covers cache for LATAM operators, not a worldwide average.

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: What operators should measure

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: Failure modes we actually see

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.
