Scheduled

The following systems and services will be impacted for up to 1.5 hours within the outage window. This activity will involve two separate outages of approximately 45 minutes each, required to fail the backend system over to the disaster recovery (DR) server and then fail the system back to the primary server after validation and testing have been completed. 

The initial outage, during which the system will be failed over to the DR server, is expected to occur between 26/05 23:00 and 27/05 00:30.
The second outage, to fail the system back to the primary server, is expected between 27/05 01:30 and 03:00

The timing of the failback activity is dependent on the successful completion and validation of the primary environment failover. As a result, the failback may commence earlier or later than the indicative timeframe outlined above. 

Note: In the event of any unplanned issues, the entire outage window may be utilised for troubleshooting, remediation or extended verification.
