On Wednesday 27th May at approximately 10am UTC we observed intermittent delays in API processing and, from approximately 12pm, delays in workflow and behavioural email processing. These delays were not fully resoled until 4pm UTC. From that time, the queues were processing normally.
We have made several changes in response to the delays seen on the 26th and 27th May and are confident that delays in email or API processing should not occur again. We monitored these queues through Thursday 27 May and will continue to do so.
Both API and email status components were updated to reflect the delays as they occurred. If you have any questions, please email us at email@example.com
