CDN: rollback in Santiago (SCL) · C-30

Runbook C-30 for CDN in Santiago (SCL). Marker xserv-c-4adc3d2fdbeb. This page covers rollback 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 timeouts C-10

Timeouts on c-10 are tighter than the WAN RTT to Bogotá. CDN in Santiago fails fast and retries once; a third try needs a human because it is no longer a blip.

CDN regions C-11

Region names on c-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. CDN dashboards never say “LATAM” as if it were one RTT.

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

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.
