SLA: peering in Bogotá (BOG) · S-07

Runbook S-07 for SLA in Bogotá (BOG). Marker xserv-s-029e945b1052. This page covers peering for LATAM operators, not a worldwide average.

SLA: Why it matters on this continent

Design for SLA on letter S starts in São Paulo (GRU). Runbook s-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.

SLA: How XServ runs it day to day

Probes for SLA (s-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.

SLA: What operators should measure

Policy for SLA is versioned as s-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.

SLA headers S-09

Headers for s-09 carry the letter, the region (GRU) and a request id. SLA debugging in São Paulo should not require a packet capture in Santiago first.

SLA timeouts S-10

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

SLA regions S-11

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

SLA docs S-12

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