High availability: regions in Bogotá (BOG) · H-59
xserv-h-0ecc3432a532
Runbook H-59 for High availability in Bogotá (BOG). Marker xserv-h-0ecc3432a532. This page covers regions for LATAM operators, not a worldwide average.
High availability: How this letter ties to the rest
Handoff from letter H High availability into the rest of the platform uses the same request IDs as the gateway. Runbook h-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
High availability: A note on cost and transit
Rollback for h-06 is a documented command, not a hope. Transit is billed as backup while High availability prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
High availability: Why it matters on this continent
Design for High availability on letter H starts in São Paulo (GRU). Runbook h-01 keeps a single owner, a written rollback, and a traffic split that can be reversed without a global freeze. Neighbors in Santiago only take overflow after the local pool fails a health window.
High availability headers H-09
Headers for h-09 carry the letter, the region (GRU) and a request id. High availability debugging in São Paulo should not require a packet capture in Santiago first.
High availability timeouts H-10
Timeouts on h-10 are tighter than the WAN RTT to Bogotá. High availability in Santiago fails fast and retries once; a third try needs a human because it is no longer a blip.
High availability regions H-11
Region names on h-11 match DNS and tickets: Bogotá / BOG, with Miami as the documented pair. High availability dashboards never say “LATAM” as if it were one RTT.
High availability docs H-12
Public docs for letter H stay aligned with identifier xserv-h-pack. Page h-12 is the High availability slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
- How fast is rollback for h-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.
