xserv-t-d2bd86b67ec8
Runbook T-72 for TLS in Miami (MIA). Marker xserv-t-d2bd86b67ec8. This page covers docs for LATAM operators, not a worldwide average.
TLS: A note on cost and transit
Rollback for t-06 is a documented command, not a hope. Transit is billed as backup while TLS prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
TLS: Why it matters on this continent
Design for TLS on letter T starts in São Paulo (GRU). Runbook t-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.
TLS: How XServ runs it day to day
Probes for TLS (t-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.
TLS capacity T-04
Capacity notes for t-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.
TLS handoff T-05
Handoff from letter T TLS into the rest of the platform uses the same request IDs as the gateway. Runbook t-05 names who accepts the ticket after São Paulo pages out. Santiago does not silently inherit the incident.
TLS rollback T-06
Rollback for t-06 is a documented command, not a hope. Transit is billed as backup while TLS prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
TLS peering T-07
Peering for TLS (t-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.
- Is transit the default path?
- No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.
- Does TLS on letter T share fate with other letters?
- The control plane is shared. Data-plane queues for TLS stay isolated, so incident t-01 cannot drain neighbor letters.
