CDN: peering in Bogotá (BOG) · C-31

xserv-c-a506aae919cc

Runbook C-31 for CDN in Bogotá (BOG). Marker xserv-c-a506aae919cc. This page covers peering for LATAM operators, not a worldwide average.

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: What operators should measure

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.

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.

How fast is rollback for c-03?
The runbook is a command plus a named owner. There is no wait for a weekly change freeze.
Is transit the default path?
No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.
