Academic Ops: Intermittent Catalog Display Issues

The Academic Ops Catalog service for US customers experienced intermittent errors between approximately 3:24 AM and 5:54 AM ET due to a temporary infrastructure issue affecting the catalog database. During this time, some users may have encountered errors when accessing catalog content. No catalog data was lost or corrupted, and the catalogs are available at this time. After investigating, we have confirmed that the system was able to recover on its own, and the catalog service is fully operational again, and scheduled catalog reindex jobs have completed.
