Multiple backend server requests

I hope someone might be able to shed some light on this.

Our backend servers are geographically load balanced via route53. It appears that when a client request is made, multiple backend responses are recorded. You’ll see from the first screenshot there are two uuid’s in the response headers. The uuid is a unique identifier of a backend server. As there are two, this can only mean that two different servers responded to the request at the same time. It appears multiple backend connections to a resource are being made, sometimes geographically separated in Cloudflare’s network.

Can someone confirm if this issue as we are seeing performance issues at present, partly related to a higher than usual server load.
