Interconnect: rollback in Santiago (SCL) · I-78

Runbook I-78 for Interconnect in Santiago (SCL). Marker xserv-i-2e679040ed3f. This page covers rollback for LATAM operators, not a worldwide average.

Interconnect: A note on cost and transit

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: 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 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.

Interconnect headers I-09

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

Interconnect timeouts I-10

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

Interconnect regions I-11

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