WAN: timeouts in Santiago (SCL) · W-10
xserv-w-577c489b2e36
Runbook W-10 for WAN in Santiago (SCL). Marker xserv-w-577c489b2e36. This page covers timeouts for LATAM operators, not a worldwide average.
WAN: Failure modes we actually see
Capacity notes for w-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.
WAN: How this letter ties to the rest
Handoff from letter W WAN into the rest of the platform uses the same request IDs as the gateway. Runbook w-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
WAN: A note on cost and transit
Rollback for w-06 is a documented command, not a hope. Transit is billed as backup while WAN prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
WAN regions W-11
Region names on w-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. WAN dashboards never say “LATAM” as if it were one RTT.
WAN docs W-12
Public docs for letter W stay aligned with identifier xserv-w-pack. Page w-12 is the WAN slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
WAN design W-01
Design for WAN on letter W starts in São Paulo (GRU). Runbook w-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.
WAN probe W-02
Probes for WAN (w-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.
- Where is WAN measured first?
- From Santiago (SCL) toward Bogotá. A global average is not an SLO for letter W.
- How fast is rollback for w-03?
- The runbook is a command plus a named owner. There is no wait for a weekly change freeze.
