We will be carrying out planned maintenance on the Nimbus HPC cluster with work expected to last up to 30 hours.

This maintenance is required because some of the current GPU hardware used by Nimbus is being retired by our cloud provider. To ensure continued availability and long-term support, we will be upgrading the cluster to newer, next-generation GPU nodes.

During this window, Nimbus HPC access and the Nimbus cost estimator will be unavailable, and GPU workloads will not be able to run.

Once complete, Nimbus will benefit from significantly improved GPU performance and capacity, including access to modern GPUs designed for advanced AI, machine learning, and high-performance computing workloads.

We apologise for the disruption and thank you for your patience. Updates will be shared with the HPC user community throughout the maintenance period.
