Hi,

When we try to retrieve specific binary FHIR resources from the sandbox FHIR API, we are receiving the following cloudfront error. It does not affect all binary resources, just certain ones (e.g. Binary/XR-203510560). Any thoughts on what is going on? Thanks!

Now they are all working fine. I'm assuming this is a volume/traffic issue on the FHIR API?

In general, the volume of requests could cause this type of issue as well as large documents (CCDs) that take longer to process. In most cases, a retry can result in the document being returned!
