Microsoft Azure Outage Disrupts Global Cloud Services
Microsoft’s Azure cloud platform experienced widespread service disruptions on Wednesday, marking the second major cloud outage within a week following Amazon’s recent downtime.
Key Takeaways
- Microsoft Azure outage began at 1600 GMT due to configuration error
- Services affected include Azure Front Door and multiple consumer platforms
- Comes just one week after major Amazon Web Services outage
- Both incidents highlight cloud dependency risks for businesses
Configuration Error Triggers Microsoft Service Disruption
Several Microsoft cloud customers faced service disruptions on Wednesday after what the company described as an “inadvertent configuration change” affecting its Azure platform. The issue began impacting systems at 1600 GMT and specifically affected Azure Front Door, Microsoft’s content delivery network service used by enterprises to enhance application performance.
Microsoft provided an update to clients at 2230 GMT, confirming it had finished deploying its “last known good” configuration. The company noted that some users might experience “intermittent failures” as the system continued recovering.
Widespread Impact on Consumer Services
The crowdsourced outage tracker DownDetector reported widespread disruptions affecting numerous consumer websites and services, including Xbox, Alaska Airlines, and Costco. Configuration adjustments are routine in technology operations, but small errors can escalate quickly due to the interconnected nature of cloud systems that propagate changes instantly to customers worldwide.
“We are currently recovering nodes and re-routing traffic through healthy nodes across our fleet. This recovery effort involves reloading configurations and rebalancing traffic across a large number of nodes to restore full operational scale,” Microsoft said.
Amazon’s Recent Cloud Outage
This incident follows last week’s major Amazon Web Services outage that left popular internet services offline for hours. The disruption affected streaming platforms including Amazon’s Prime Video and Disney+, along with Perplexity AI, Fortnite, Airbnb, Snapchat, and Duolingo.
Mobile telephone services and messaging apps Signal and WhatsApp were affected in Europe, while people also reported problems accessing Amazon’s own e-commerce shop. Several banks, including Lloyd’s, pointed to AWS as the source of their service issues.
Amazon later confirmed on a status page that the affected system had returned to “pre-event levels,” though noted it could take hours to clear the data backlog caused by the problem.
