Is Amazon CloudFront down?

What Amazon CloudFront does - and how it fails

Amazon CloudFront is AWS’s global CDN - the front door for websites, APIs, and media. Because it runs at hundreds of edge locations, CloudFront incidents tend to be geographic (elevated errors in some regions of the world) or configuration-driven (a bad deployment propagating to the edge).

• Elevated 5xx rates at a subset of edge locations
• Increased cache-miss rates pushing load onto origins
• Slow or stuck configuration/invalidation propagation
• Origin-side failures that look like CloudFront errors to users

• [RESOLVED] Increased 5xx Errors

  Between 12:45 AM and 4:18 AM PDT, we experienced increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity. Our engineers were automatically engaged and immediately began investigating the root cause. By 2:57 AM PDT, we identified the root cause of the issue as an internal constraint on the fleet that manages connections to private VPC origins. When this constraint was reached, the system responsible for distributing routing configuration to our network processors failed to load the updated configuration data correctly, affecting routing of VPC Origin connections. At 3:52 AM PDT, we took multiple mitigation actions that led to to full recovery at 4:18 AM PDT. Now that the issue has been mitigated, customers who temporarily changed their origin type can safely revert these changes. Customers utilizing other origin types were not affected by this issue. The issue has been resolved and the service is operating normally.
