Microsoft has attributed a major global outage affecting its services to a technical error that occurred during an upgrade of its network infrastructure. The company said the incident was not related to a cyberattack or the use of artificial intelligence, adding that most services had already been restored.
“We sincerely apologize for the inconvenience this incident has caused our customers and partners. We understand the trust they place in our services and take this responsibility very seriously. We are currently seeing an overall recovery and stabilization across all our services,” Microsoft said in a statement on X.
According to the company, the problem originated during an earlier expansion of network capacity but only became apparent after a recent change to network settings.
“This was a technical issue not related to cyber or AI / agents. The incident was introduced by an issue during an earlier network capacity upgrade that surfaced following a recent network change. We have addressed the underlying issue and continue to restore service to remaining customers and regions,” Microsoft said.
The recovery was carried out in stages because of the high load, with specialists checking system stability after each phase.
“While this took longer, it helped ensure a stable restoration. We will provide a full post-incident report once our review is complete,” the company said.
The global outage began on November 12 and affected tens of thousands of users around the world. Problems disrupted Microsoft’s Outlook email service, Teams video-conferencing platform, Copilot AI assistant and other products. The outage affected not only individual users but also government agencies and major companies.
