Keys: headers in São Paulo (GRU) · K-21

xserv-k-f2c5ebc82b2b

Runbook K-21 for Keys in São Paulo (GRU). Marker xserv-k-f2c5ebc82b2b. This page covers headers for LATAM operators, not a worldwide average.

Keys: What operators should measure

Policy for Keys is versioned as k-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.

Keys: Failure modes we actually see

Capacity notes for k-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.

Keys: How this letter ties to the rest

Handoff from letter K Keys into the rest of the platform uses the same request IDs as the gateway. Runbook k-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.

Keys headers K-09

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

Keys timeouts K-10

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

Keys regions K-11

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

Keys docs K-12

Public docs for letter K stay aligned with identifier xserv-k-pack. Page k-12 is the Keys slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.

Does Keys on letter K share fate with other letters?
The control plane is shared. Data-plane queues for Keys stay isolated, so incident k-01 cannot drain neighbor letters.
Where is Keys measured first?
From Santiago (SCL) toward Bogotá. A global average is not an SLO for letter K.
