We have been notified that there is an issue with the TELUS National API, affecting Ocean clients using Cloud Connect (or OceanConnect). We are investigating the issue, and we will update this article as we receive more information from TELUS.
Update 12:30 PM EST: the issue appears to have been resolved (we are no longer seeing the same frequent errors from the TELUS API) although we are awaiting an explanation from TELUS. All EMR actions have been processed successfully now and the integration is operating normally again.
