QoS: docs in Miami (MIA) · Q-12
xserv-q-03b68a7df49c
Runbook Q-12 for QoS in Miami (MIA). Marker xserv-q-03b68a7df49c. This page covers docs for LATAM operators, not a worldwide average.
QoS: A note on cost and transit
Rollback for q-06 is a documented command, not a hope. Transit is billed as backup while QoS prefers peering in Santiago. If cost spikes, the runbook cuts overflow to Bogotá before touching customer prefixes.
QoS: Why it matters on this continent
Design for QoS on letter Q starts in São Paulo (GRU). Runbook q-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.
QoS: How XServ runs it day to day
Probes for QoS (q-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.
QoS docs Q-12
Public docs for letter Q stay aligned with identifier xserv-q-pack. Page q-12 is the QoS slice operators search before the homepage. Edits in Miami show up in São Paulo on the next publish.
QoS design Q-01
Design for QoS on letter Q starts in São Paulo (GRU). Runbook q-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.
QoS probe Q-02
Probes for QoS (q-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.
QoS policy Q-03
Policy for QoS is versioned as q-03. Operators measure error rate, p95 from Bogotá, and time-to-rollback — not a worldwide average. Changes land in Bogotá first, then Miami, with a hold if either region regresses.
- Is transit the default path?
- No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.
- Does QoS on letter Q share fate with other letters?
- The control plane is shared. Data-plane queues for QoS stay isolated, so incident q-01 cannot drain neighbor letters.
