India's Sovereign Digital Infrastructure Survives Global Microsoft Outage

A global Microsoft 365 outage on November 12-13 disrupted government and financial services across 74 countries for nearly 21 hours, but India's core administrative and banking systems continued operating without interruption. India's resilience stems from its sovereign digital infrastructure, built over a decade under the National Informatics Centre (NIC). Central ministries use dedicated domestic email and e-Office platforms on government-controlled servers, while financial systems like UPI operate on segregated national networks with strict data localisation mandates. While private Indian firms faced temporary disruptions, the state's uninterrupted functioning has highlighted New Delhi's model of technological self-reliance. The contrast has prompted global reassessment of over-dependence on concentrated foreign cloud ecosystems, positioning India's NIC framework as a blueprint for national cyber resilience.
