Microsoft outage disrupts key Australian services
A widespread disruption of Microsoft services began Friday morning and lasted approximately 18 hours before recovery efforts resumed gradually. The company confirmed that the issue was a 'technical problem' unrelated to cyber-attacks or artificial intelligence agents.
The outage impacted millions of users worldwide, including organisations in healthcare, education, government, finance, and public administration across Australia.
Impact on critical institutions
Several hospitals and health clinics reported disruptions to digital prescribing systems. According to the Australian Medical Association (AMA), some facilities reverted to paper-based scripts because multifactor authentication for software access requires connectivity to Microsoft-supported email accounts.
Courts in South Australia and Victoria experienced outages affecting their internal communication systems. Schools nationwide also faced interruptions as many rely on Microsoft 365 tools for administrative operations.
Service NSW, a one-stop agency providing services to residents and businesses, advised customers to delay visits to service centres during the outage period due to system unavailability.
Federal government affected
National security agencies were impacted by the disruption. Mike Burgess, head of ASIO (the domestic spy agency), stated that while some levels of its infrastructure were affected, 'they operate on multiple levels' and confirmed it was not a complete failure.
Economic consequences
Experts warn the incident could result in billions of dollars in economic losses for Australia’s small business sector. Ashwin Pal, partner at RSM Australia, noted that many businesses activated disaster recovery plans but lacked fallback options.
Ashwin Pal: "A protracted event like this can easily be the straw that breaks the camel's back for smaller entities."
Pal added he is 'flabbergasted' as to how such an outage occurred, citing that Microsoft had pushed out a software change without adequate testing procedures.
Calls for systemic review
The Australian Computer Society has renewed calls for urgent government assessment of which critical IT systems depend on single providers. Chief executive Prins Ralston said: 'Australians who couldn’t get paid, couldn’t send an invoice, or couldn’t reach a government service this morning are entitled to be worried.'
Similar disruptions were reported globally: UK healthcare services faced interruptions; British police urged the public not to report crimes online and instead call in person. In Japan, shipping company Sagawa Express could not accept online reservations at airports and train stations, while pharmaceutical firm Taisho shifted operations to phone-based order handling.
Market reaction
On Wall Street, Microsoft shares dipped slightly during trading hours—down 1.1% to $516.86—as market participants reacted to the incident's scale and implications.
In a statement, Charles Lamanna, executive vice-president of Copilot at Microsoft, said: 'We regret that today’s outages caused disruptions for our customers, and we are working to address the issue.'
The company has not identified specific root causes beyond server configuration issues related to maintaining Microsoft 365 services. No evidence suggests malicious activity or intentional disruption.
