Notice
ASX will conduct a business continuity test in the production ASX 24 environment on Saturday 28 June 2025. It is expected that all trading participants will participate in the test.
What do I need to do by when?
- Registrations via Appendix 1 should be completed and returned to ASX Customer Technical Support (CTS) by close of business on Friday 20 June 2025 to confirm participation for the test. CTS will not accept any registrations or confirmations of any connections to be used in the test beyond this date.
- The test is limited to ASX 24 connections; there will be no access to Genium Clearing during the test period.
- Access to ASX 24 multicast data protocol (MDP) will be enabled for the test. MDP users who do not want to participate in the test should ensure their sessions remain disconnected after ASX 24 end of day processes commence on Saturday 28 June 2025 until the conclusion of testing and the rollback is completed, ready for the earlier system start-up time of 13:00 Sunday 29 June 2025.
- Configuration changes made during the test, including password changes, will be rolled back at the end of the test and will not be available in production on Monday 30 June 2025.
- The trading date for transactions performed during the test will be Saturday 28 June 2025. These transactions will not be available on ASX 24 on Monday 30 June. Participants and vendors need to remove any 28 June transactions from their applications on completion of the test.
- Timings and activities of the day will be published in real-time on the system status page.

Test Confirmation
On completion of the test, customers must email CTS their test status, advising of either a successful completion or a list of outstanding issues.
ASX intends to have all failover scenarios completed as early as possible in the test schedule to allow customers to complete their validation. The remaining test window is to allow for ASX internal system validations separate to the failover scenarios.
Confirmations can be sent as soon as these scenarios have been completed on the day, but should be sent by no later than 17:00 AEST.
The ASX 24 platform will start up earlier than usual on Sunday 29 June at 13:00 to facilitate any early connectivity testing.
It is suggested that where required test participants liaise with their vendors prior to the test to ensure readiness.
