Where is Uptime measured first?

From Santiago (SCL) toward Bogotá. A global average is not an SLO for letter U.

How fast is rollback for u-03?

The runbook is a command plus a named owner. There is no wait for a weekly change freeze.

Uptime: timeouts in Santiago (SCL) · U-70

Runbook U-70 for Uptime in Santiago (SCL). Marker xserv-u-33b6170a3020. This page covers timeouts for LATAM operators, not a worldwide average.

Uptime: Failure modes we actually see

Capacity notes for u-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.

Uptime: How this letter ties to the rest

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

Uptime: A note on cost and transit

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

Uptime headers U-09

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

Uptime timeouts U-10

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

Uptime regions U-11

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

Uptime docs U-12

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