TLS: peering in Bogotá (BOG) · T-31

Runbook T-31 for TLS in Bogotá (BOG). Marker xserv-t-d121db148e78. This page covers peering for LATAM operators, not a worldwide average.

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: How XServ runs it day to day

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: What operators should measure

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.

TLS capacity T-04

Capacity notes for t-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.
