We are receiving slow response time (10-20 seconds) from an application running through Red Hat 3scale API Management on OpenShift Container Platform (OCP). Upon further examination of
tcpdumps captured across the whole platform, it appears there are
DNS level queries to resolve internal OCP pods - such as the connection between APIcast and
backend-listener - that are being sent to external DNS instead of being resolved locally by OCP.
