Maintenance activity: Database and Systems security patching
18:00, Friday 18 June – 23:59, Sunday 20 June
There will be a full system/service outage whilst we apply security patches to databases and systems. Further details can be found on UCAS.com.
During this maintenance we will also be updating choices with an RBD date of 13/07/2021 to 06/07/2021 and choices having an RBD date of 14/09/2021 to 29/09/2021. Please note that this may result in a larger number of updated records being in your next import from us once services have been restored.
If you have any questions, please contact the Service Delivery Management (Technical) team.
