AWS CloudFront outage serves errors instead of websites

UPDATED 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.
