This appears to be an issue with outbound traffic from the Kubernetes pods.

The api service that handles these requests makes an outbound SMTP request to send the feedback to us as an email. This involves DNS resolution followed by a TCP connection.

Currently neither DNS resolution nor TCP connections outside of the Kubernetes cluster appear to be possible. It may be that the routing table on the pods is incomplete.

/ $ nslookup github.com
Server:		10.96.0.10
Address:	10.96.0.10:53

;; connection timed out; no servers could be reached

/ $ wget github.com
wget: bad address 'github.com'
/ $ route -n

A default route on a non-link-local-only network is expected (and is not currently found) in the routing table, as shown above.

This appears to have been resolved; albeit without any (re)configuration actions taken. Perhaps it's an intermittent / timing-based issue? Some logs have been collected from the calico-node in the cluster in case further investigation is required.
