TLS: timeouts in Santiago (SCL) · T-70

xserv-t-52b06727fa5e

Runbook T-70 for TLS in Santiago (SCL). Marker xserv-t-52b06727fa5e. This page covers timeouts for LATAM operators, not a worldwide average.

TLS: Failure modes we actually see

Capacity notes for t-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.

TLS: How this letter ties to the rest

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

TLS: A note on cost and transit

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

TLS regions T-11

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

TLS docs T-12

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

TLS design T-01

Design for TLS on letter T starts in São Paulo (GRU). Runbook t-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.

TLS probe T-02

Probes for TLS (t-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.

Where is TLS measured first?
From Santiago (SCL) toward Bogotá. A global average is not an SLO for letter T.
How fast is rollback for t-03?
The runbook is a command plus a named owner. There is no wait for a weekly change freeze.
