Hello Hummingbird user community, we will be offline for a few days in early January to perform our winter maintenance on the cluster.

We will be offline starting Thursday, January 2nd at 8am and will resume service by (latest) Sunday, January 5th at 8pm. Hopefully this will actually be a shorter window than scheduled, as we only need to do minor OS updates across the cluster (no big moves and shifts this time).

All cluster access will be shut off starting at 8am, so please ensure all jobs and file transfers are completed prior to this time. I will put the queues into DRAIN mode (no new jobs) the morning of the Tuesday December 31st at 8am (this will allow any remaining jobs 48 hours to complete).

If you have any questions or concerns, please reach out on Slack or open a ticket by emailing hummingbird@ucsc.edu.
