Runbook N-36 for Network in Miami (MIA). Marker xserv-n-734614ada234. This page covers docs for LATAM operators, not a worldwide average.

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 peering N-07

Peering for Network (n-07) prefers the IX fabric that already carries last-mile ISPs in Bogotá. Session counts and prefix limits are on the same page as the Miami backup path.

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.

Network headers N-09

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

Network timeouts N-10

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

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.
