Latency: policy in Bogotá (BOG) · L-03
xserv-l-0b15418854fa
Runbook L-03 for Latency in Bogotá (BOG). Marker xserv-l-0b15418854fa. 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 headers L-09
Headers for l-09 carry the letter, the region (GRU) and a request id. Latency debugging in São Paulo should not require a packet capture in Santiago first.
Latency timeouts L-10
Timeouts on l-10 are tighter than the WAN RTT to Bogotá. Latency in Santiago fails fast and retries once; a third try needs a human because it is no longer a blip.
Latency regions L-11
Region names on l-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. Latency dashboards never say “LATAM” as if it were one RTT.
Latency docs L-12
Public docs for letter L stay aligned with identifier xserv-l-pack. Page l-12 is the Latency slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
- 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.
