Microsoft 365 services suffered a massive global outage on Friday creating severe operational disruptions across Asia-Pacific and Europe.
The failure rippled through adjacent sectors, impacting police forces, health services, and government bodies worldwide. Anthropic revealed issues with its services, while the Bank of England confirmed internal communication problems. In the UK, the National Health Service reported that communication systems took the hit even though clinical and operational networks kept running.
New employee onboarding stalled because Intune struggled to handle device enrolment, check-ins, and compliance checks. Third-party platforms relying on core Microsoft infrastructure also collapsed.

The incident highlighted the systemic danger of relying on a single technology provider for critical back-end operations.
“This should be a wake-up call for every organisation. Businesses need to ensure they can continue operating when critical technology becomes unavailable, without relying entirely on a single system or provider,” Marijus Briedis, Chief Technology Officer at NordVPN, told Computerworld.
Briedis added that secure backup communications and tested contingency plans separate minor inconveniences from major crises.
Microsoft worked to resolve the issue throughout the day, but status page updates remained unclear and fixes proceeded slowly. Investigators attributed the collapse to a faulty software update containing an undisclosed bug.
Dawn Butler argued that the Outlook failure demonstrated why the UK must develop independent technological capabilities rather than depending entirely on US Big Tech for core infrastructure and artificial intelligence.
Enterprise purchasers are expected to invest heavily in non-Windows hardware like Macs and iPhones to boost disaster resilience. IT departments are also searching for alternative device management platforms to replace Intune.
The global Outlook outage is a reminder of why digital sovereignty matters. We need a Parliamentary, London and UK wide strategy to invest in our own capability and take control of our digital future. We cannot rely on US Big Tech for our digital infrastructure, including AI.

Business users planned to establish secondary email channels, configure emergency offline credentials, set up backup routines for Microsoft 365 data, and review service-level agreements to check for financial compensation clauses.
“Secure backup communications, tested contingency plans, and robust recovery procedures can make the difference between a temporary inconvenience and a major operational crisis,” Briedis told Computerworld.
