Peering: headers in São Paulo (GRU) · P-33
xserv-p-f0bf4edd9e6b
Runbook P-33 for Peering in São Paulo (GRU). Marker xserv-p-f0bf4edd9e6b. This page covers headers for LATAM operators, not a worldwide average.
Peering: What operators should measure
Policy for Peering is versioned as p-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.
Peering: Failure modes we actually see
Capacity notes for p-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.
Peering: How this letter ties to the rest
Handoff from letter P Peering into the rest of the platform uses the same request IDs as the gateway. Runbook p-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
Peering headers P-09
Headers for p-09 carry the letter, the region (GRU) and a request id. Peering debugging in São Paulo should not require a packet capture in Santiago first.
Peering timeouts P-10
Timeouts on p-10 are tighter than the WAN RTT to Bogotá. Peering in Santiago fails fast and retries once; a third try needs a human because it is no longer a blip.
Peering regions P-11
Region names on p-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. Peering dashboards never say “LATAM” as if it were one RTT.
Peering docs P-12
Public docs for letter P stay aligned with identifier xserv-p-pack. Page p-12 is the Peering slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
