What "runs at national scale" actually means underneath dsFatoora.
Load-balanced regional processing hubs with automatic failover if one goes down mid-peak.
Branches/POS terminals queue locally so brief connectivity loss never blocks a transaction.
Latency and rejection-rate spikes trigger alerts before they become customer-visible incidents.
Active signing certificates are cached at the hub level to avoid a round-trip on every single transaction.
A tested recovery plan for hub-level and regional outages, not just a promise on a slide.
Infrastructure is sized and tested above observed peak volumes, not just to meet them.
