[Yale ArchivesSpace] ArchivesSpace Downtime this Weekend - March 8-9, 2025

[Kidd, Mary]

Hi YULASpace,

I wanted to provide a brief update on an unexpected ArchivesSpace outage that occurred over the weekend in case it impacted any of your work.

On Saturday, March 8, 2025, at 9:00 PM ET, ASpace experienced a Solr connection failure due to a known daylight saving time (DST) bug (see ANW-1229<https://archivesspace.atlassian.net/jira/software/c/projects/ANW/issues/ANW-1229>, ANW-2120<https://archivesspace.atlassian.net/browse/ANW-2120>). Solr is responsible for indexing within the system, and while ArchivesSpace itself remained technically running, it was largely unusable, particularly for API-driven processes.

Since the application was still responding at a basic level, Lyrasis' automated monitoring did not detect the failure, and the issue went unflagged until it was manually reported by me.

Lyrasis applied a fix at 6:50 PM ET on Sunday, March 9, and full functionality was restored by 7:22 PM ET. We are reviewing monitoring gaps for sites running ASpace versions that are still vulnerable to this bug. If you notice any lingering issues or have questions about how this may have affected your workflows, feel free to reach out.

Best,
Mary
