Microsoft outage exposes risks of relying on major tech providers

A global Microsoft Outlook outage on Friday disrupted services for thousands of users, highlighting risks of over-reliance on major tech providers. Experts say the incident exposed significant vulnerabilities in communication systems. The outage affected Microsoft 365 services including Outlook, Teams, and Copilot for over half a day, impacting businesses and government systems in Singapore. Microsoft attributed the issue to servers becoming unexpectedly unavailable, though it ruled out malicious activity and reported broad recovery by Saturday. Experts warn that redundancy does not guarantee resilience when services share infrastructure. They advise organisations to identify critical systems, test disruption scenarios, and develop fallback plans, as dependence on single vendors creates cascading risks across the global economy.
