Mar 22, 2023
06:54: The issue with jobs being slow to start appears to have improved. We will continue to monitor the situation.
Mar 21, 2023
21:31: Maintenance is complete. We will continue to monitor the system. We have noticed that some jobs are slower than usual to start, we will attempt to determine the root cause behind this in the morning.
18:16: Maintenance has started on UCloud and will be ongoing for the next few hours. We will update when the maintenance is complete. We do not expect any disruption to user jobs.
Mar 15, 2023
14:55: The u1-standard machine is currently running at 100% utilization. As a result, you may have to wait before your job starts. Update: UCloud had resources available again around 18:00 Wednesday.
Mar 10, 2023
12:53: Nearly 100% of all UCloud resources are currently in use. This is causing some jobs to immediately transition to a failed state due to our scheduler refusing to accept any new jobs.
Update: UCloud had resources available again at around 21:00 Friday.
Mar 3, 2023
10:02: UCloud is currently experiencing higher load than usual. This means that you may experience longer wait times than usual. In particular, it can be hard to start jobs which require large machine types. If you are having trouble starting a job, then try selecting a smaller machine type. The high load is also causing the output of applications to not always appear. We are working on a fix for this issue. If you are running one of the applications which depend on this and the output don’t appear, then please contact support. The support team should be able to retrieve any information you may need from the output. This in particular affects applications such as MinIO and Rsync Server which depend on this output.

10:50: We have applied several patches since yesterday. Preliminary results suggest that the service is more stable now, but we will continue to monitor the situation.
Feb 13, 2023
15:01: We are still trying to solve stability issues with UCloud caused by the maintenance operation last week. Some apps are more affected by this issue, such as RStudio and JupyterLab. If you experience a disconnect (or 403 errors), please close the app and press the "Open interface" button again.
Feb 9, 2023

14:21: We have deployed some mitigations against the observed errors. We will continue to observe the system for errors.
12:46: We are observing some errors related to the maintenance yesterday. We are aware of these problems and are monitoring the situation closely.
Feb 7, 2023
12:56: Access to UCloud has been restored. The cluster currently has fewer nodes than normal. As we are still in the process of moving some nodes to a new system. We expect this capacity to return to normal levels by the end of tomorrow.
GPU machines in the Type 1 (SDU) system will remain unavailable until they have been fully migrated (expected by end of tomorrow).
12:04: The migration has been completed. We are running some additional tests to check the system.
07:58: We have started scheduled maintenance to migrate the DeiC Interactive HPC provider to a new and improved system.
Feb 1, 2023
11:07: Performance has stabilised but we are still seeing slower than usual queries. We are working on improving performance.
09:54: We are experiencing issues related to the compute sub-system of UCloud.
Jan 10, 2023
15:46: We have observed some file-system sporadic instability on UCloud. We are monitoring the situation, but we are still considering the system operational.
Dec 22, 2022
12:04: Around 11:31 we experienced around 10 minutes of downtime due to a network reconfiguration.
Dec 16, 2022
12:44: The Virtual Machines hosted at AAU may be slow and less responsive between Dec 14 and Dec 31 as AAU ITS is performing scheduled maintenance.
Dec 6, 2022
10:16: An issue with application output has been resolved.
09:13: The last application section has returned correctly to UCloud.
