Mercado Online outage highlights vulnerability of Zandorian e‑commerce

Customers reported failed purchases worth ₣1.2 billion, while logistics partners saw container bookings stalled, affecting the deep‑water berth’s cargo handling schedule. The disruption rippled through supply chains that rely on rapid e‑commerce fulfillment.
