Following our earlier update, we are still seeing intermittent connection issues causing mail processing and delivery delays for customers on the ZA grid.

We believe this connection issue is being caused by an unusual volume of emails attempting delivery and causing contention issues within our environment. This means some emails are being automatically retried because the service they're attempting to reach is intermittently busy and unable to respond promptly. We are seeing these emails correctly deliver on a later retry.

Our team is focused on resolving the issue, and we apologise for the continued inconvenience. Further updates will be provided as soon as possible.

In an effort to improve email backlog processing times our ongoing mitigation may cause you to see a short period of time where there is a temporary increase in deferred messages. These messages will retry according to the sending server’s retry schedule, and we expect these emails to successfully deliver on a later retry. Thank you for your understanding as we work through this issue.

The previously mentioned deferral period has concluded and we are continuing with our investigation. We continue to see mails deliver on retry attempts. Thank you for your patience whilst we continue to investigate. Further updates will be posted here.
