Court livestreams were also affected, and schools asked parents to report student absences by phone.<\/li>\n<\/ul>\n<p>The impact extended to other industries. According to Reuters, email support services used by Indian airlines IndiGo and Akasa Air were affected, while some financial firms in Taiwan experienced disruptions to fund management activities.<\/p>\n<p>The outage also affected Microsoft connectors used by OpenAI and Anthropic, disrupting their integration with Microsoft 365 services.<\/p>\n<h4><strong>Microsoft struggles to restore affected servers<\/strong><\/h4>\n<p>Microsoft initially attributed the disruption to elevated infrastructure loads across multiple regions. It later clarified that the increased load was not caused by a general rise in traffic but by a large number of servers becoming unexpectedly unavailable, shifting demand onto the remaining infrastructure.<\/p>\n<ul>\n<li>Further investigation found that a core process on the affected servers was becoming overwhelmed, causing the servers to stop responding and contributing to capacity loss.<\/li>\n<li>The company attempted to reduce the impact by pausing deployments, moving traffic away from affected infrastructure and restarting servers.<\/li>\n<li>However, some servers became unresponsive again after traffic was redirected to them, complicating the recovery process.<\/li>\n<\/ul>\n<p>Microsoft later reported that some affected servers had been returned to service and remained stable, while traffic was being redirected through alternative pathways where possible.<\/p>\n<p>However, the company said these measures had not delivered sustained recovery and that it was considering additional actions to improve infrastructure stability.<\/p>\n<p>Microsoft said it was not aware of any malicious activity causing the disruption, while Australian Home Affairs and Cyber Security Minister Tony Burke said the company did not believe it was dealing with a cyberattack.<\/p>\n<h4><strong>Previous outages expose businesses\u2019 reliance on cloud services<\/strong><\/h4>\n<p>The latest disruption is not the first time outages affecting major technology infrastructure providers have interrupted business operations globally.<\/p>\n<p>In November 2025, <a href=\"https:\/\/nairametrics.com\/2025\/11\/18\/cloudflare-network-outage-disrupts-millions-of-websites-globally\/\">Nairametrics reported that a major Cloudflare outage disrupted millions of websites globally,<\/a> including Nigerian websites and digital services.
