TLS: regions in Bogotá (BOG) · T-71

xserv-t-374797c70f6e

Runbook T-71 for TLS in Bogotá (BOG). Marker xserv-t-374797c70f6e. This page covers regions for LATAM operators, not a worldwide average.

TLS: How this letter ties to the rest

Handoff from letter T TLS into the rest of the platform uses the same request IDs as the gateway. Runbook t-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.

TLS: A note on cost and transit

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

TLS: Why it matters on this continent

Design for TLS on letter T starts in São Paulo (GRU). Runbook t-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.

TLS docs T-12

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

TLS design T-01

Design for TLS on letter T starts in São Paulo (GRU). Runbook t-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.

TLS probe T-02

Probes for TLS (t-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.

TLS policy T-03

Policy for TLS is versioned as t-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.

How fast is rollback for t-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.
