Is transit the default path?

No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.

Does Network on letter N share fate with other letters?

The control plane is shared. Data-plane queues for Network stay isolated, so incident n-01 cannot drain neighbor letters.

Network: A note on cost and transit

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

Network: Why it matters on this continent

Design for Network on letter N starts in São Paulo (GRU). Runbook n-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.

Network: How XServ runs it day to day

Probes for Network (n-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.

Network handoff N-05

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

Network rollback N-06

Network peering N-07

Network cache N-08

Cache rules for Network on n-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.
