On the evening of 28 October 2026, a processor compatibility update was applied to our virtual infrastructure platform to support new compute hosts. After the change, our automated workload-balancing service attempted to move some virtual machines between hosts. These moves could not complete, and a small number of client virtual machines were placed in an error state between 20:22 on 28 October and 04:22 on 29 October 2026 (SAST). Services on the affected virtual machines were unavailable from that point.
The issue was identified on the morning of 29 October 2026. From 08:42, our engineers shut down, migrated and restarted each affected virtual machine, and all were restored and verified. No data was lost.
To complete the update, the remaining virtual machines will be restarted during scheduled maintenance tonight, 29 October 2026, from 20:00 to 00:00 (SAST): https://status.irontree.co.za/incidents/3t8z99r97d8s
We are reviewing our change process to include automated platform services in impact assessments. We apologise for the disruption. If you have any questions, please contact our support team at vps@irontree.co.za.
