QoS: peering in Bogotá (BOG) · Q-31
xserv-q-975860b8d77c
Runbook Q-31 for QoS in Bogotá (BOG). Marker xserv-q-975860b8d77c. This page covers peering for LATAM operators, not a worldwide average.
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: What operators should measure
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.
QoS rollback Q-06
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 peering Q-07
Peering for QoS (q-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.
QoS cache Q-08
Cache rules for QoS on q-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.
QoS headers Q-09
Headers for q-09 carry the letter, the region (GRU) and a request id. QoS debugging in São Paulo should not require a packet capture in Santiago first.
- How fast is rollback for q-03?
- The runbook is a command plus a named owner. There is no wait for a weekly change freeze.
- Is transit the default path?
- No. Peering in Miami is default; transit to São Paulo is overflow and is billed that way.
