An unknown number of businesses in Australia and overseas have reportedly been hit by an outage to Microsoft 365 services, which, it has been suggested, is a good warning against operational dependency on a solitary technology.

The software giant tweeted late on Tuesday (29 January) that it was “investigating” an issue that was reportedly locking some users out of their accounts.

“We’re investigating an issue in which users may be unable to access Microsoft 365 services. We’re working to remediate the issue. More details can be found in the admin center [sic] under MO172692 or at http://status.office.com,” it said in the post.


Several users subsequently replied to the tweet, commenting that they were unable to reach the status page either, or even the admin centre to report their difficulties.

Many suggested the problem appeared to be a DNS issue.


Microsoft Australia has been contacted to comment on the issue and the extent to which it impacted local users.

Garrett O’Hara, principal technical consultant at email services firm Mimecast, was highly critical of the software, complaining that Wednesday’s out “is just another in a slew of outages plaguing the platform”.

He said that it should serve as a reminder for all businesses about the risks of an over-reliance on one particular software or technology.

“While the 365 outage is fresh in our minds, it is worth businesses taking a few minutes out to do a ‘back of an envelope calculation’ of what the outage cost them… the collective cost of downtime will run into millions of dollars in lost productivity,” Mr O’Hara said.



“No organisation should trust a single cloud supplier without an independent cyber resilience and continuity plan to keep connected and prepared during unplanned, and planned, outages.”
