Microsoft restores services after 24-hour global outage

Summarised from 30 outlets · 132 reports · Updated 14 Nov, 23:31 · Archive

Microsoft said on Saturday it had fully restored all services following a global outage lasting more than 24 hours that disrupted governments, hospitals, police and businesses across at least 70 countries.

Microsoft said on Saturday morning it had fully restored its services following a global outage that lasted more than 24 hours. The company posted on its Microsoft 365 status page: 'We have completed our efforts to address the underlying issue of the incident and restored service to the remaining impacted customers and regions.'

The outage began around midday Thursday (12:25pm ET) and 6pm GMT Thursday evening in the UK. It affected more than 70 countries and impacted services used by more than 430 million people worldwide, including Outlook email, Teams messaging, OneDrive storage and Copilot AI. Downdetector recorded more than 7.4 million reports of problems globally.

In the UK, the disruption was severe. The NHS experienced 'serious' and 'widespread' disruption across hundreds of hospitals, GP surgeries and community health services, with more than 1 million NHS staff unable to access the NHS.net Connect system. Hospital and surgery staff resorted to paper-based records to maintain patient care. Police forces reported difficulties in referring patient details during 999 calls. Courts, schools, councils and pharmacies were also affected, with the National Pharmacy Association warning of delays in medication supply.

Globally, governments including Japan, Singapore and Australia reported operational impacts. Airlines warned customers of communication delays. Trading firms experienced delays and some companies could not publish earnings on schedule. Emergency services, courts and businesses worldwide were forced to activate contingency and disaster recovery plans, with many organisations having no digital backup.

Microsoft said Friday the cause was 'a technical issue not related to cyber or AI agents', introduced by a problem during a network capacity upgrade that surfaced after a recent network change. The company ruled out a cyberattack. As services recovered, Microsoft set email queue times to 48 hours to ensure all messages sent during the outage would eventually be delivered.

UK government cyber minister Baroness Lloyd of Effra said the incident mainly affected back-office functions, with contingency measures activated. She acknowledged 'limited reports of impact on frontline service delivery' such as 999 calls and transport networks. Experts noted the outage was one of the longest in Microsoft's history and the second major Microsoft disruption in 2024, highlighting global reliance on a small number of major technology companies for essential services and infrastructure.
