Identified
All users accounts that were locked out during the issue have been unlocked and users should now be able to access the application.
We have identified the cause of the issue and are looking into applying a fix so that the calendar can be enabled again. We will then look to begin restoring other services (Audit and Exports).
Posted Nov 09, 2026 - 11:48 GMT
Update
We are seeing performance increases while the Calendar is turned off.
As part of our investigation we turned off other areas of the system that remain impacted: audit data will be delayed - no data will be lost, and exports will be delayed. We are looking into users who were unable to login and will look to unlock their accounts who were affected by this issue.

Update
We are temporarily disabling the calendar view from loading appointments. Users can view the appointments for a patient by searching for that patient and navigating to the “appointments” tab. Users will see errors when loading the calendar.
We continue to investigate the cause of slow application performance.
Posted Nov 09, 2026 - 11:16 GMT
Update
We paused ability to view appointments, including the calendar, between 10:54 and 10:55. We see an improvement over that time.
We are working with our system hosting provider to understand performance issues we have with out database. We are also now narrowing our investigation to appointment handling.
Posted Nov 09, 2026 - 11:02 GMT
Update
To investigate if we have an issue with Appointments we need to turn off the ability to view Appointments for 1 minute.
So far it has been possible to view the calendar. For this 1 minute window it will not be possible to view Appointments or the Calendar. Users will see an error.
