Interconnect: design in São Paulo (GRU) · I-25

xserv-i-beaf1b8571b1

Runbook I-25 for Interconnect in São Paulo (GRU). Marker xserv-i-beaf1b8571b1. This page covers design for LATAM operators, not a worldwide average.

Interconnect: Why it matters on this continent

Design for Interconnect on letter I starts in São Paulo (GRU). Runbook i-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.

Interconnect: How XServ runs it day to day

Probes for Interconnect (i-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.

Interconnect: What operators should measure

Policy for Interconnect is versioned as i-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.

Interconnect handoff I-05

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

Interconnect rollback I-06

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

Interconnect peering I-07

Peering for Interconnect (i-07) prefers the IX fabric that already carries last-mile ISPs in Bogotá. Session counts and prefix limits are on the same page as the Miami backup path.

Interconnect cache I-08

Cache rules for Interconnect on i-08 keep language-correct objects near Miami. São Paulo is a sibling cache, not an origin. TTLs are short enough that a bad asset does not live through a weekend.

Does Interconnect on letter I share fate with other letters?
The control plane is shared. Data-plane queues for Interconnect stay isolated, so incident i-01 cannot drain neighbor letters.
Where is Interconnect measured first?
From Santiago (SCL) toward Bogotá. A global average is not an SLO for letter I.
