[Increased 5xx Errors] Service degradation: Increased 5xx Errors

We continue working to resolve the increased 5xx errors for CloudFront customers utilizing VPC Origins connectivity. Customers utilizing other origin types remain unaffected by this issue. Based on our investigation, we believe the root cause is related to a packet processing subsystem responsible for routing requests from CloudFront's edge locations to resources within customer VPCs. We continue to recommend that customers who are able to do so temporarily change their origin type to resolve the errors. We will provide another update by 4:15 AM PDT, or sooner if additional information becomes available.
