On November 25, millions of Microsoft users around the world suddenly encountered a serious interruption. This problem has lasted all day and disrupted the email and online meeting systems of many businesses.
Accordingly, users began reporting problems related to Outlook and Teams at around 9:00 a.m. (21:00 p.m. Vietnam time), through Downdetector - a website that specializes in monitoring Internet incidents globally. It is known that the peak of the incident recorded more than 5,000 reports during the above period.
Microsoft quickly confirmed the problem, saying the cause stemmed from a change in software that affected a large number of the companys servers.
Despite launching a fix on November 25, Microsoft admitted that the recovery process was going slower than expected. About five hours later, reports of the incident continued to increase.
As of the morning of November 26, Microsoft said the fix had been rolled out to about 98% of affected users. However, some servers are still unstable and need more time to operate again.
However, Outlook's web version is still having problems for a small number of users. Microsoft has pledged to monitor and thoroughly fix the remaining problems throughout the day.
With millions of businesses dependent on Microsoft products, this incident causes many difficulties, because many jobs today rely on email and online meetings. A Microsoft representative said: "We understand the impact of this incident on businesses and are working tirelessly to restore the service as soon as possible."
This is not the first time a major technology incident has had a widespread impact. In July this year, an error-prone software update from cybersecurity company CrowdStrike caused the biggest incident in the history of the IT industry.
