Due to this technical glitch in Microsoft 365, millions of users around the world had to face huge problems, due to which popular services like Outlook, Teams and Copilot were completely stalled. After this widespread global crisis has subsided, the company has now completely restored its services and has also officially revealed the real reason behind this major technical glitch. Let us know in detail what was the real reason for this mega outage and how much of its impact was seen across the world. Microsoft's mega outage finally ends, hitting at least 74 countries Microsoft has officially announced in its final status update that the company has successfully fixed the root cause of this incident and all the affected services have been fully restored. This technical crisis was so severe that it directly affected users in at least 74 countries. Due to this mega outage, the functioning of companies, government offices, hospitals, courts and airlines in many countries around the world was completely derailed. The situation had become so serious that many institutions were forced to abandon modern digital means and resort to phone lines, paper records and fax machines to conduct their essential day-to-day operations. The technical problem started on November 12, know why it took the whole day. This entire problem started on November 12 when users in the US and other regions suddenly started complaining that they were not able to access their Exchange Online Mailboxes. Microsoft first officially acknowledged the problem at 5:54 pm GMT (11:24 pm IST). Just 13 minutes later, the company had issued a warning that users from any region of the world could fall prey to this technical glitch. The biggest and challenging task was to keep the servers running and stable once they came back up. Microsoft engineers said that the servers that were being brought back into service could have crashed again when there was a sudden increase in traffic. The company's engineers worked on a war footing on multiple fronts simultaneously. They limited the types of traffic coming to the affected infrastructure, reset some critical servers back to their old and secure configuration, applied necessary patches to authentication and routing components, and added several virtual machines for additional capacity. Additionally, the situation was further complicated by the huge pile of millions of emails (emails queued) already accumulated on the servers due to non-delivery. What was the real reason for this mega outage? There was a lot of speculation in social media and the tech market about the reasons behind this global disruption, but Microsoft has clarified that this incident was not caused by any kind of cyber attack or Artificial Intelligence (AI). The company deeply regrets this disruption. A Microsoft spokesperson said in an official statement that the incident was actually caused by a technical issue that occurred during an earlier network upgrade and network capacity increase work, which suddenly emerged after a recent network change. The reason was initially attributed to heavy traffic load in company updates on In fact, many servers had suddenly stopped working due to failed automated health checks, causing all their workload to fall on the servers that were still running, thus increasing the pressure on one server after another. The impact of the outage was visible across the world including India, many areas had to face problems. Microsoft 365 services have more than 450 million paid commercial subscriptions worldwide, due to which its reach is very wide. The impact of this outage was also seen in India, where email support services of IndiGo and Akasa Air were affected for some time, although Air India maintained its operations smoothly by using alternative routes. National Health Service (NHS) staff in the United Kingdom (UK) had to use paper documents to keep records of patients, while a judge in Manchester had to send jurors home. Some companies in Japan resumed using old faxes, and electric truck maker Workhorse Group had to postpone the announcement of its quarterly results to November 16. Microsoft has promised that it will make public a detailed report after a thorough internal review of this entire matter is completed.
