Virtual IP: rollback in Santiago (SCL) · V-18

xserv-v-330760a33524

Runbook V-18 for Virtual IP in Santiago (SCL). Marker xserv-v-330760a33524. This page covers rollback for LATAM operators, not a worldwide average.

Virtual IP: A note on cost and transit

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

Virtual IP: Why it matters on this continent

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: How XServ runs it day to day

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 headers V-09

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

Virtual IP timeouts V-10

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

Virtual IP regions V-11

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

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.

Where is Virtual IP measured first?
From Santiago (SCL) toward Bogotá. A global average is not an SLO for letter V.
How fast is rollback for v-03?
The runbook is a command plus a named owner. There is no wait for a weekly change freeze.
