Freezer storage restoration
Resolved - This incident has been resolved.
Oct 15, 09:26 NZDT
Update - We are continuing to monitor for any further issues.
Sep 4, 16:19 NZST
Monitoring - Thank you for your patience while we’ve worked to bring Freezer back online. As part of our recovery from the Tamaki Data Centre’s cooling failure incident on 29 July, we have now completed comprehensive testing of our tape library and tape media. Our results indicate that the tapes are healthy.

Freezer is now available for use.

We encourage you to contact support@nesi.org.nz if you notice anything out of the ordinary or have concerns about your data.

We will continue to monitor Freezer as usage levels return to normal.
Sep 4, 16:07 NZST
Update - We are working with our vendors to test the health of our tape library and tape media following the cooling incident at the TDC. We will provide updates to project leaders on the status of your data once known, but we expect this may take some time. Further updates may be provided as we work through this process. Our apologies for any concern or inconvenience this might cause.
Aug 11, 08:57 NZST
Investigating - Following the cooling incident at Tāmaki Data Centre (https://status.nesi.org.nz/incidents/yznlzzntjgpp) we are performing thorough health checks on the tape media used for Freezer storage.

As of now we do not have a timeline for the restoration of the Freezer storage service, but we will provide updates when we have sufficient information.

HPC SSH access gateway, Thursday 6 October
Completed - The scheduled maintenance has been completed.
Oct 6, 10:30 NZDT
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Oct 6, 09:30 NZDT
Scheduled - We're updating the gateway servers that SSH connections to the HPC pass through on their way to the login nodes, to improve their security and reliability.

A dropped connection doesn't stop anything running on the login nodes. If you use tmux or screen, reattach to your session after reconnecting.

Your SSH connection will be interrupted. Twice during the window, new connections may fail for a few seconds while we update each of the nodes. If a connection fails, wait a moment and try again.

Please note that your running and queued jobs are not affected.
