The following systems and services will be impacted for up to 1.5 hours within the outage window. This will consist of 2 separate, 45 minute outages; these outages are required to switch a backend system to into its backup / disaster recovery (DR) server and then back again once the upgrade on the primary server has been completed.
We anticipate the initial outage when the system is failed over to its backup / disaster recovery (DR) server to happen between 09/05 23:00 – 00:05, with the second outage occurring when the system is failed back to the primary server occurring between 10/05 06:00 – 07:00.
The failback activity timing is dependent on the successful completion of the Primary environment upgrade and validation. The failback may commence earlier or later than the indicative time shown above.
Note: In the event of a rollback, the entire outage window may be utilised.

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.
