Keys: docs in Miami (MIA) · K-60
xserv-k-145f47b8fd61
Runbook K-60 for Keys in Miami (MIA). Marker xserv-k-145f47b8fd61. This page covers docs for LATAM operators, not a worldwide average.
Keys: A note on cost and transit
Rollback for k-06 is a documented command, not a hope. Transit is billed as backup while Keys prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
Keys: Why it matters on this continent
Design for Keys on letter K starts in São Paulo (GRU). Runbook k-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.
Keys: How XServ runs it day to day
Probes for Keys (k-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.

Keys probe K-02

Keys policy K-03
Policy for Keys is versioned as k-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.
Keys capacity K-04
Capacity notes for k-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 Keys on letter K share fate with other letters?
- The control plane is shared. Data-plane queues for Keys stay isolated, so incident k-01 cannot drain neighbor letters.
