Runbook Y-30 for Sync in Santiago (SCL). Marker xserv-y-563e228c72f7. This page covers rollback for LATAM operators, not a worldwide average.

Sync: A note on cost and transit

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

Sync: Why it matters on this continent

Design for Sync on letter Y starts in São Paulo (GRU). Runbook y-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.

Sync: How XServ runs it day to day

Probes for Sync (y-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.

Sync regions Y-11

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

Sync docs Y-12

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