Please see below, notice from Nexus regarding an upcoming system update:
On Wednesday, 22nd February 2023, the Nexus system will be getting some essential updates and maintenance. While these updates happen you will not be able to access that system.
The Nexus team will be working as quickly as possible to get the updates up and running, however the system will be unavailable on this day from 4:00pm and up to 10:00pm - but hopefully, the update will be finished a lot sooner.
If there is anything you may require from Nexus, you'll need to login and download or record before the update takes place.
