AWS CloudFront outage serves errors instead of websites

Amazon Web Services (AWS) is experiencing another outage after a CloudFront issue began throwing 5xx errors, knocking a string of websites and online services offline across multiple regions. According to AWS, the issue began at 0145 PDT (0945 UTC) this morning and affects CloudFront customers using VPC Origins. This is a relatively new CloudFront feature that lets customers serve applications running behind private load balancers through CloudFront without exposing their back-end infrastructure
