Following the upgrade to the system over the weekend, there is some further essential maintenance that needs to be carried out. It is therefore best that the system is taken down.
This upgrade to the system needed to be carried out at this time to be completed before the centralised return updates were done for the department at the end of the year.
Your co-operation and patience is very much appreciated and we apologise for this downtime.
Update: Tuesday 9AM
We are working as fast as possible to get the system back live and expect to have it live by lunchtime at the latest today.
