DNS: capacity in Miami (MIA) · D-64

Runbook D-64 for DNS in Miami (MIA). Marker xserv-d-4562d08bc8ff. This page covers capacity for LATAM operators, not a worldwide average.

DNS: Failure modes we actually see

Capacity notes for d-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.

DNS: How this letter ties to the rest

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

DNS: A note on cost and transit

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