“The reason for this outage has been identified and updates have been released to resolve the issue,” said an official communication. The technology partner of the Government of India, National Informatics Center (NIC), that provides technology-driven solutions to Central and State Governments fortunately remains unaffected.
The global outage, which roughly began around 10 am, saw airports, airlines, banks, brokerages, critical services take a hit. Airports have switched to ‘manual’ mode of operations temporarily to tide over the crisis. Airlines, airports in India are issuing handwritten boarding passes to passengers.
Several brokerages have reported disruption in services which left traders/investors in the lurch with no trades being executed and people clamouring for compensation.
A few media houses also took a hit with UK’s Sky News going entirely off air following the development.
It’s unclear what has caused the outage, but some businesses, including Australian energy company AGL, blamed an update from security firm CrowdStrike.
Microsoft said the impacted services include: PowerBI, Microsoft Fabric, Microsoft Teams, Microsoft 365 admin center, Microsoft Purview and Viva Engage. It acknowledged the issues with its Azure services and Microsoft 365 apps, said, “Our services are still seeing continuous improvements while we continue to take mitigation actions.”
