State University:
Reported disruptions affecting Microsoft Planner and AI agents.
10. Possible Technical Causes
o Dr
Timothy Wood, a computer science professor at George Washington University,
suggested several possible explanations:
§ A
faulty or improperly implemented software update.
§ Problems
affecting multiple servers.
§ A
malfunction in the system responsible for monitoring server health.
o He
explained that even if the servers themselves were operating correctly, a
malfunctioning monitoring system could incorrectly identify them as faulty.
o He
compared the situation to a broken thermometer incorrectly indicating that
everyone has a fever.
11. Broader Concerns About Cloud Dependence
o The
outage has highlighted the extensive dependence of businesses, governments and
individuals on a relatively small number of global cloud-service providers.
o A
disruption in Microsoft's infrastructure can simultaneously affect email,
communications, business administration, customer support, healthcare and AI
services.
o The
incident has renewed concerns about business continuity and the need for
alternative systems.
The Microsoft outage demonstrates the
systemic risks arising from global dependence on centralised cloud
infrastructure. Even without a cyberattack, technical failures affecting a
major service provider can disrupt businesses, airlines, hospitals, government
agencies and AI companies across multiple countries.

The
global outage affecting Microsoft’s sprawling set of software tools stretched into
a second day on Friday, leaving businesses and workers around the world without
crucial tools.
The
company said after 10 p.m. Eastern on Thursday that changes meant to repair the
problem were “not taking as expected.”
The
outage affects software used by hundreds of millions of users, impairing corporate
offices, government agencies and individuals who rely on the company’s suite of
services to send emails, draft letters, conduct virtual meetings and many other
daily functions.
“It
shows how reliant we are on these cloud systems,” said Dr.
Timothy Wood, a professor of computer science at George Washington University.
It
began on Thursday afternoon, as workers and offices around the world began reporting
issues with a range of Microsoft 365’s tools and apps, including email and chat
software. By Friday, some airlines and artificial intelligence companies also said
they were affected by the outage.
Around
1 p.m. on Thursday, the outage tracker Downdetector showed
that more than 130,000 users were experiencing problems with Microsoft Outlook,
the workplace messaging app Microsoft Teams, the A.I. assistant Microsoft Copilot and the Microsoft Store.
In
an update posted on social media around 5 p.m., Microsoft said it was “opening all
available pathways to restore service, as our actions taken thus far have not provided
the anticipated relief.”
A
Microsoft executive, Charles Lamanna, said on social media
that there was no indication that the outage was the “result of malicious or cyber
activity.” As of 2.30 a.m., the company said some users might still be unable to
connect to its services.
Companies
affected by the outage include the Indian low-cost carrier Indigo, which said that
its email support services had been disrupted. South Africa’s CemAir said it was experiencing “system disruptions” due to
the outage. Neither had reported flight disruptions as of Friday morning.
A.I.
companies OpenAI and Anthropic also said they were experiencing
issues with their connections to Microsoft services on Friday.
On
Thursday evening, the Arapahoe County Sheriff’s Office in Colorado said jail officials
could not receive emails to process bond payments for detained individuals because
of the outage.
A
hospital system in Toronto, Unity Health, said in a statement that its staff members
were having trouble sending and receiving email, and asked patients to call instead
to arrange appointments. Pennsylvania State University described how Microsoft’s
services, such as its planner and A.I. agents, were impaired by the outage.
Microsoft
had said that part of its infrastructure was “experiencing elevated load across
multiple regions.”
The
company later said that it had begun redistributing traffic across its broader worldwide
infrastructure to help balance the load and that it was restarting affected servers.
The
outage prompted waves of frustration, anger — and glee. On social media and Reddit,
some embraced the system shortage, which allowed them to step away from work, while
others expressed concern over how they might be able to work in the future.
Mr.
Wood said the outage might have stemmed from a botched software update, problems
with various servers or a system that checks the servers’ health.
Microsoft’s
servers could be functioning properly, but the system responsible for checking on
their maintenance could be malfunctioning, Mr. Wood said.
“The
thermometer is broken,” he said, “and anyone you test looks like they have a fever.”
