Share

Word is going around that a cyber attack caused the Microsoft Teams and Office 365 outage but is malicious activity truly the culprit?

Microsoft had just experienced a major outage in its Teams, Outlook, and Office 365 services. While the issue has already been addressed by the tech giant, the cause of the outage is still a mystery to most people.

The services provided by the tech company are an integral part of society today, especially during this pandemic. A major disruption to their services would no doubt encumber countless of businesses and people worldwide.

Many suspected a cyber attack to be the cause of the outage but is that really the case?

The early hours of the Microsoft outage

Around 5 P.M. E.T. on Monday, many Outlook, Teams, Office 365 users began experiencing service issues. At the same time, Sharepoint, OneDrive, Exchange, and Azure users were having sign-in issues.

Microsoft then took to Twitter to confirm that significant outages had affected many of their services.

According to the reports, several users were unable to log-in. Every time they tried to do so, an error message would pop up informing them of a problem. The service issues continued on through to the evening.

Damage control

By this time, many were already wondering about the cause of such service disruption. It didn’t take too long before Microsoft posted another update.

According to them, a change they had recently made on their system seems to have caused the issues. The company also revealed that they started to roll out the changes in order to mitigate the impact of the issue.

Unfortunately, rolling back the changes did not have any significant effect on the issue. The tech giant admitted that there was no increase in successful connections and thus needed to investigate the root cause of the problem.

No malicious activity involved

Around this time, the word on the vine is that Microsoft may have suffered from a cyber attack, hence the disruption of their services. The company’s failure to quickly resolve the issue further gave rise to this suspicion.

However, Microsoft itself had confirmed that the issue hadn’t been caused by a cyber attack.

“At this time, we’ve seen no indication that this is the result of malicious activity,” representatives for the company said in a statement to CNN.

Resolution

The issue only took a positive turn when the company decided to reroute traffic to an alternate route. Further updates revealed that user experience had started to improve and that their system is starting to recover. The majority of their services had started to recover and that they’re only monitoring residual issues left behind by the outage.

Finally, at around 10 P.M. E.T., Microsoft announced that the residual issues had finally been resolved.
