Anycast: policy in Bogotá (BOG) · A-63

Runbook A-63 for Anycast in Bogotá (BOG). Marker xserv-a-64aba91b0c28. This page covers policy for LATAM operators, not a worldwide average.

Anycast: What operators should measure

Policy for Anycast is versioned as a-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.

Anycast: Failure modes we actually see

Capacity notes for a-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.

Anycast: How this letter ties to the rest

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