Runbook Y-52 for Sync in Miami (MIA). Marker xserv-y-3adcc2a7b31e. This page covers capacity for LATAM operators, not a worldwide average.
Sync: Failure modes we actually see
Capacity notes for y-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.
Sync: How this letter ties to the rest
Handoff from letter Y Sync into the rest of the platform uses the same request IDs as the gateway. Runbook y-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
Sync: A note on cost and transit
Rollback for y-06 is a documented command, not a hope. Transit is billed as backup while Sync prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
Sync policy Y-03
Policy for Sync is versioned as y-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.

- Is transit the default path?
- No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.
- Does Sync on letter Y share fate with other letters?
- The control plane is shared. Data-plane queues for Sync stay isolated, so incident y-01 cannot drain neighbor letters.
