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.

WAN: timeouts in Santiago (SCL) · W-22

Runbook W-22 for WAN in Santiago (SCL). Marker xserv-w-458cc174012b. 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 timeouts W-10

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

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.
