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.

Virtual IP: timeouts in Santiago (SCL) · V-46

Runbook V-46 for Virtual IP in Santiago (SCL). Marker xserv-v-038fb569e6f1. This page covers timeouts for LATAM operators, not a worldwide average.

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: 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 rollback V-06

Virtual IP peering V-07

Peering for Virtual IP (v-07) prefers the IX fabric that already carries last-mile ISPs in Bogotá. Session counts and prefix limits are on the same page as the Miami backup path.

Virtual IP cache V-08

Cache rules for Virtual IP on v-08 keep language-correct objects near Miami. São Paulo is a sibling cache, not an origin. TTLs are short enough that a bad asset does not live through a weekend.

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.
