IUCAT and other campus-wide outage information

Information about IU Notices and Downtimes including IUCAT downtime is available at Status.IU.

Outages & Downtime for Subscription Resources (e-journals, databases, etc) 

This page lists the electronic journals and databases for which a report has been made that the title cannot be reached by users on the Bloomington campus. Titles are listed in alphabetical order.

When a vendor of a collection of electronic journals reports problems in connecting to all or a large number of its journals (often several hundred titles), the problem is noted, but all of the titles in the collection cannot be listed individually.

Titles are removed as soon as the problem has been resolved.
