Network maintenance: Libraries and online services not accessible on 17 and 18 February
Due to large-scale maintenance in the heart of the Leiden University network, all Leiden University Libraries (UBL) library locations will be closed on 17 and 18 February 2024.
None of the UBL online services that require log in with a ULCN account will be available. Users will not have access to, for example, the online Catalogue, Digital Collections, the UBL website or online resources such as databases and journals.
The university network will be unavailable from 9.00 a.m. on Saturday, 17 February. This will last all day and much of Sunday, 18 February.
Faster, safer and future-proof
With the network update, Leiden University will once again be able to rely on its network being a safe environment for all users, now and in the future. The network bandwidth will also be increased and network speeds will increase. For the latest updates about the maintanance, go to our X (previously Twitter) or Facebook.
