Final update regarding the disruption on 7 May

The issues caused by the disruption on 7 May, which resulted in a large number of staff accounts being set to inactive, have now almost all been resolved. As some of our colleagues were recently away for Ascension Day, they may be experiencing the effects of the disruption for the first time this week.

In theory, some staff members may still be experiencing issues with the (private) channels in Teams – owners of the Teams environments can add these colleagues back. Another potential issue relates to the accessibility of (shared) calendars and availability.

If you encounter any problems, we recommend restarting your own laptop first. If this does not help, you can of course contact the ISSC Helpdesk (helpdesk@issc.leidenuniv.nl or +31 (0)71 527 8888). The staff there are ready to assist you.

The ISSC Helpdesk has also received enquiries regarding the cause of the disruption. We would like to reiterate that the disruption was an unintended consequence of technical maintenance work.

 

Update 15:30 12-05-26

Since last Thursday’s disruption, in which a large number of staff accounts were temporarily deactivated, the ISSC has been working hard to recover all systems. All accounts have now been reactivated, and profile pages on the website should all be visible again shortly.

The online environments have been closely monitored since Thursday. The current picture is that no new widespread issues have emerged since the disruption; there have been a few isolated cases, which have been dealt with immediately once reported to the ISSC Helpdesk.

As mentioned, all profile pages should be back online shortly. If individual pages prove to be inaccessible after today, please contact the ISSC helpdesk at 071 527 8888. The team can also assist with other questions about the disruption and its effects. Staff who have not restarted their laptops in the past few days are advised to do so.

Further updates will be shared here as soon as new information becomes available.

Update 13:30 11-05-26

Over the past weekend, we continued to work hard to address the consequences of the disruption that occurred last Thursday evening. As a result, a large number of staff accounts were set to inactive.
All accounts have now been reactivated, and all staff should once again be able to use Office 365. This includes programmes such as Word, Excel and Teams. Sending emails via Exchange should also be possible again.
Unfortunately, this does not mean that all issues have now been resolved. For example, not all profile pages on our website are visible again. Furthermore, the use of all online applications is not yet running smoothly. The ISSC team is working hard to resolve this as quickly as possible.
Staff members encountering problems are advised to restart their own laptop first. Only then will it be possible to regain access to their account and other services. Those who continue to experience issues can, of course, contact the ISSC Helpdesk. The staff there are ready to assist you: 071-727 8888
Regarding email traffic: please note that affected users did not receive any emails during the disruption. The sender has been notified of this. These emails will therefore need to be resent.
We are very sorry that not everything is yet back to normal. ISSC asks the last group of affected users to bear with us a little longer.
As soon as there are any new developments to report, an update will be posted here
 

Update 10:15 11-05-26

If you encounter any problems, we recommend that you first restart your device; if this does not work, please contact the ISSC Helpdesk.

Update 15:45 08-05-26

Since Thursday evening, intensive work has been underway to address the consequences of the disruption that occurred at that time, which caused a large number of employee accounts to be set to inactive.

ISSC reports that the reactivation of these accounts is progressing smoothly: a large number of employees have already regained access to their accounts. Those who are still unable to access their accounts are kindly asked for a little more patience. We hope to have all accounts reactivated as soon as possible.

Employees who should already have regained access to their account and/or services such as Teams, but are still experiencing issues, are advised to first restart their laptop. Only after doing so will it be possible to regain access to their account and other services.

We understand that this disruption is causing problems for our employees, and we regret that this has happened. People who continue to experience certain IT-related issues after their account has been reactivated can contact the ISSC Helpdesk after the weekend. The staff there will be ready to assist you.

As soon as there are new developments to report, an update will be posted here.

We are currently experiencing issues logging in to several services. 

The phone queues for the Helpdesk and the ASSC service desk are currently very busy. If you are having trouble logging in, this is likely due to the ongoing technical issue. There is no need to call us about this. If we indicate that the issue has been resolved and you are still unable to log in, please contact us.
