A major Microsoft outage has disrupted Outlook services for millions of users worldwide, leaving many unable to access their email accounts. The incident has once again brought attention to the reliability of digital infrastructure and the growing dependence of businesses on uninterrupted technology services. Over the past two years, several major technology outages have affected businesses and users across the globe. From the Microsoft-CrowdStrike outage in July 2024 to disruptions involving Google Cloud, ChatGPT, Amazon Web Services (AWS) and Cloudflare in 2025, these incidents have highlighted the impact of disruptions across critical digital platforms.
In July 2024, a global IT outage involving Microsoft and cybersecurity firm CrowdStrike disrupted airport operations worldwide. Several airport systems were affected, forcing airlines and airport authorities to resort to manual processes, including issuing handwritten boarding passes. In June 2025, a Google Cloud outage affected several services, including YouTube, Gmail, Google Meet and Google Nest. Acknowledging the disruption, Google stated: “Following a disruption to a number of Google Cloud services, all products have now been fully restored.” The same month, ChatGPT users across the world reported delayed responses and service disruptions. OpenAI acknowledged the issue and said its engineers were working to restore normal operations.
Another major disruption occurred on 20 October 2025, when an AWS outage affected several online services. A DNS resolution failure involving DynamoDB in the US-EAST-1 region disrupted access to critical AWS services, including IAM and DynamoDB Global Tables, resulting in widespread downtime and delays. AWS subsequently restored the affected DNS functionality.
In November 2025, Google Meet reportedly faced service disruptions in India, with users from cities including Delhi, Kolkata, Ahmedabad, Mumbai, Bengaluru and Chennai reporting difficulties accessing the platform. Downdetector received more than 1,700 reports of service unavailability. In December 2025, a Cloudflare outage affected access to several popular websites and services, including Canva, LinkedIn and Groww. Even Downdetector experienced accessibility issues as it relied on Cloudflare’s infrastructure.
These incidents have highlighted how disruptions at major technology infrastructure providers can have a cascading impact on businesses, digital services and everyday operations. Commenting on the lessons businesses should take from these outages, Ajai Kumar, Chief Information Officer, DE-CIX India, said: “Recent hyperscaler outages remind us that no organisation is immune to digital disruptions. Businesses must look beyond uptime commitments and build resilient connectivity strategies with alternate network paths and contingency plans to ensure business continuity. We are consciously speaking of digital emergency kit and advance preparation with redundant routes. It’s time for organisations to prepare in advance then last minute firefighting. These are no less critical than real time disaster preparedness, the risks of digital disasters are very critical and severe.”
