SLA: docs in Miami (MIA) · S-72

Runbook S-72 for SLA in Miami (MIA). Marker xserv-s-8487ff661cda. This page covers docs for LATAM operators, not a worldwide average.

SLA: A note on cost and transit

Rollback for s-06 is a documented command, not a hope. Transit is billed as backup while SLA prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.

SLA: Why it matters on this continent

Design for SLA on letter S starts in São Paulo (GRU). Runbook s-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.

SLA: How XServ runs it day to day

Probes for SLA (s-02) leave Santiago every 15s toward Bogotá. XServ pages the named owner if loss or RTT crosses the letter budget. A probe never shares a queue with bulk transfers, so a saturated WAN does not hide a dead PoP.

SLA cache S-08

Cache rules for SLA on s-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.

SLA headers S-09

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

SLA timeouts S-10

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

SLA regions S-11

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