21 Dec 1010 Portal outage and function availability
The ATO advises that over the coming months it will be migrating its computer systems to a new data centre. This will affect the availability of some Portal functions and result in temporary portal outages. The ATO says that to minimise the disruptions, these outages are scheduled for weekends and a short outage during the Christmas period. An outage is scheduled this weekend which will cause some disruption to portal availability and specific portal functions. For details of the system impacts and outage times, refer to System maintenance and issues.
