Virtual IP: headers in São Paulo (GRU) · V-69
xserv-v-9225ecd8b140
Runbook V-69 for Virtual IP in São Paulo (GRU). Marker xserv-v-9225ecd8b140. This page covers headers for LATAM operators, not a worldwide average.
Virtual IP: What operators should measure
Policy for Virtual IP is versioned as v-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.
Virtual IP: Failure modes we actually see
Capacity notes for v-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.
Virtual IP: How this letter ties to the rest
Handoff from letter V Virtual IP into the rest of the platform uses the same request IDs as the gateway. Runbook v-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
Virtual IP docs V-12
Public docs for letter V stay aligned with identifier xserv-v-pack. Page v-12 is the Virtual IP slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
Virtual IP design V-01
Design for Virtual IP on letter V starts in São Paulo (GRU). Runbook v-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.
Virtual IP probe V-02
Probes for Virtual IP (v-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.
Virtual IP policy V-03
Policy for Virtual IP is versioned as v-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.
