What caused this issue? Why were so many major websites affected by it? And what steps can you take to reduce the impact on your own applications? ‍

Automating chaos engineering with Terraform eliminates manual setup across environments by enabling you to version control your entire chaos infrastructure, from service discovery to security governance policies. The Harness Terraform provider supports end-to-end automation including Kubernetes infrastructure setup, custom image registries, Git-based ChaosHub management, and granular security controls that ensure safe experiment execution in production.

On October 29th, 2025, Azure Front Door suffered an outage that impacted Microsoft services on a global level, including Microsoft 365, Outlook, Xbox Live, Copilot, and more. It also affected Microsoft Azure, meaning companies like Costco, Starbucks, and Alaska Airlines ran into issues for both customer-facing and internal systems. The root of the issue was a misconfiguration in the data plane for Azure Front Door and the Azure Content Delivery Network.

It’s now easier than ever to start testing Kubernetes with Dynatrace and Gremlin. With a new strategic integration, Kubernetes services set up in Dynatrace are automatically discovered in Gremlin to make testing set up simple and fast. At a time when AI is driving massive expansions in infrastructure and dramatically increasing deployment speed, being able to set up and test new services quickly is more important than ever. ‍

On October 19th and 20th, 2025, the AWS region US-EAST-1 suffered a massive outage. What started with a 3-hour Amazon DynamoDB outage from a DNS issue led to an Amazon EC2 outage that lasted an additional 12 hours before normal service was restored. Over the course of the outage, there were over 17 million outage reports as companies like Snapchat, Roblox, Amazon, Reddit, Venmo, and more were impacted.

Harness Chaos Engineering now runs natively on GKE Autopilot. A simple allowlist configuration enables you to test resilience on Google's managed Kubernetes without sacrificing security or requiring workarounds. Google's GKE Autopilot provides fully managed Kubernetes without the operational overhead of node management, security patches, or capacity planning. However, running chaos engineering experiments on Autopilot has been challenging due to its security restrictions. We've solved that problem.
