High availability: timeouts in Santiago (SCL) · H-58

Runbook H-58 for High availability in Santiago (SCL). Marker xserv-h-3335869ca4f0. This page covers timeouts for LATAM operators, not a worldwide average.

High availability: Failure modes we actually see

Capacity notes for h-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.

High availability: How this letter ties to the rest

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

High availability: A note on cost and transit

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

High availability headers H-09

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

High availability timeouts H-10

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

High availability regions H-11

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

High availability docs H-12

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