xserv-l-8db94cc48dab
Runbook L-39 for Latency in Bogotá (BOG). Marker xserv-l-8db94cc48dab. This page covers policy for LATAM operators, not a worldwide average.
Latency: What operators should measure
Policy for Latency is versioned as l-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.
Latency: Failure modes we actually see
Capacity notes for l-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.
Latency: How this letter ties to the rest
Handoff from letter L Latency into the rest of the platform uses the same request IDs as the gateway. Runbook l-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
Latency handoff L-05

Latency rollback L-06
Rollback for l-06 is a documented command, not a hope. Transit is billed as backup while Latency prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
Latency peering L-07
Peering for Latency (l-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.
Latency cache L-08
Cache rules for Latency on l-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.
- How fast is rollback for l-03?
- The runbook is a command plus a named owner. There is no wait for a weekly change freeze.
- Is transit the default path?
- No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.
