CDN: docs in Miami (MIA) · C-48

Runbook C-48 for CDN in Miami (MIA). Marker xserv-c-0333644f9fc2. This page covers docs for LATAM operators, not a worldwide average.

CDN: A note on cost and transit

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

CDN: Why it matters on this continent

Design for CDN on letter C starts in São Paulo (GRU). Runbook c-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.

CDN: How XServ runs it day to day

Probes for CDN (c-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.

CDN docs C-12

Public docs for letter C stay aligned with identifier xserv-c-pack. Page c-12 is the CDN slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.

CDN design C-01

CDN probe C-02

CDN policy C-03

Policy for CDN is versioned as c-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.
