CDN: timeouts in Santiago (SCL) · C-46

xserv-c-2e7870f35085

Runbook C-46 for CDN in Santiago (SCL). Marker xserv-c-2e7870f35085. This page covers timeouts for LATAM operators, not a worldwide average.

CDN: Failure modes we actually see

Capacity notes for c-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.

CDN: How this letter ties to the rest

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

CDN: A note on cost and transit

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

CDN cache C-08

Cache rules for CDN on c-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.

CDN headers C-09

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

CDN timeouts C-10

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

CDN regions C-11

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

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