Due to exceptionally high demand in two clusters in our TXL and FRA datacenters, we have temporarily paused Managed Kubernetes Automated Maintenance. To ensure that clusters remain operational without interruption during updates, Automated Maintenance requires temporary cluster "cloning", which increases resource consumption. As most maintenance windows are scheduled to run over the weekend, resource demand peaks sharply during these periods. To protect cluster stability and prevent service degradation, we have paused maintenance for the affected clusters. Any maintenance scheduled from today onward will not run until we resume. We know automated Kubernetes maintenance is an important feature of our platform, and we did not take this decision lightly. We are expanding capacity in the affected clusters as a high priority and will update this page as soon as maintenance resumes.

- resolved Aug 25, 2026, 05:24 PM UTC
We have enabled maintenance again in all DCs.
