Update timeline

  1. monitoring May 13, 2026, 10:59 AM UTC

    Between 07:30 UTC to 08:56 UTC, 13th May 2026 a Gateway outage occurred for customers that manifested as inbound and outbound server status being 'Unavailable'. This has since been resolved and the server statuses should now all be 'Available' once more. Emails in the queue are expected to clear themselves automatically. We are still working through how this happened and will share further details as soon as possible. Please open a support case if you are still experiencing delays. Thank you for your on-going patience.

  2. monitoring May 13, 2026, 02:05 PM UTC

    Between approximately 07:30 UTC and 08:36 UTC, some customers experienced an outage where inbound and outbound server statuses were shown as 'Unavailable'. The issue was caused by a capacity limitation encountered during the application of a routine security patch. This has been fully resolved — server statuses should now show as 'Available'. Any emails queued during the incident are expected to be delivered automatically without intervention. No data loss occurred, and we anticipate minimal delivery delays. We apologise for any disruption caused, please open a support ticket if you have any questions. We will close this status as resolved after 24 hours monitoring.
