OCLC will be performing infrastructure upgrades in their US data centers.
This work is scheduled from April 10 2026, 23:00 ET through April 11 2026, 07:00 ET and may temporarily affect access to some OCLC products and services in all regions.
The main service interruption is expected during the first several hours of the maintenance window, with possible intermittent service degradation for the remainder of the window. Due to the complexity of this operation, the maintenance window may extend beyond the anticipated schedule.
For the most current information (including the schedule in your local time zone) and to subscribe to updates, please visit the OCLC System Status Dashboard. The Dashboard will be updated to reflect any changes during the maintenance period.
