Failover ops runbook when volume is already live
At live volume, name who may reorder rails, who watches prepaid burn, and who owns client-facing status during a failover switch — white-label roles before the pager.
Failover after Live is an ops incident with money and client trust on the line. Name three owners before the pager: who may flip rail order, who watches burn and stop-lines, and who owns what buyers see while rails switch.
IOSOR is white-label prepaid. USD 20 funds the pilot floor; soft review near USD 1,000/month is when unordered flips get expensive. Prerequisites: Primary rail fails: ordered backup without double-debit, Failover gates before any Live badge, Partial failover send without double charge. Distinct from SMS routing at scale — here we own people and authority on a live switch.
Roles before the pager rings
Write roles while the corridor is calm. Name a rail-order owner, a burn owner for wallet ceilings, and a status owner for client UI and webhook copy. Hats may overlap on a tiny team; keep them separate on paper so a 02:00 incident does not invent an org chart.
| Role | Owns | Must not |
|---|---|---|
| Rail order | Documented primary → backup flips | Silent reorder without ticket + export |
| Burn | Stop-lines, ceilings, top-up alerts | Blind “keep sending” past wallet floors |
| Status | White-label outcomes during switch | Upstream brand strings in buyer UI |
| Incident lead | Timeline, hand-offs, postmortem | Skipping ledger export after the event |
Who may reorder rails at volume
Only the named rail-order owner (or pre-delegated backup) may change the live sequence: update the written path, smoke the new backup under pilot keys if time allows, then cut over — not fan-out to every rail or invent a path in chat.
Every reorder at volume is an audit event: who, when, corridor, why. Money identity still follows Partial failover send without double charge. If Live gates were never green, pull volume first — do not fix order in production.
Burn watch and wallet stop-lines
Failover storms burn prepaid faster than steady primary. The burn owner watches Wallet stop-lines before production and prepaid spend control. Stop-lines pause or shed before the pilot wallet empties — not after soft USD 1,000/month review already hurts.
Export burn in the incident: units switched, settles vs releases, corridors hit. Burn without matching client volume is a money bug (double settle or spray), not routing noise.
Client status ownership during a switch
Buyers see one honest IOSOR trail: accepted, pending, delivered, failed, needs attention. The status owner updates copy and support macros so mid-flight hops do not look like duplicate sends or invented Delivered. Ops logs may name the fulfilling rail; client surfaces must not.
Buyer / ops checklist at live volume
- Rail-order, burn, and status owners named before Live volume?
- Only the named owner may reorder — with ticket and export?
Start with IOSOR
Name three owners before the pager rings: who may reorder rails, who watches burn and wallet stop-lines, who owns the white-label status the buyer sees. Rehearse a switch while volume is already live: force the hop, confirm one debit, confirm stop-lines would hold, confirm the wording. An unnamed runbook at volume is an expensive pager.
IOSOR takeaway
A volume runbook is named owners and stop-lines, not a latency formula.
Do: write who may flip rails and who talks to the buyer while volume is already Live.
Don’t: let the first pager invent the rail order, or hide a second debit behind “we failed over”.
