Optus has scheduled a maintenance window that may briefly affect some services next week.

• What it is: planned network maintenance scheduled for Wednesday 9 September, between 9pm and 10pm AEST.
• Who is affected: Optus business and consumer customers in areas covered by the maintenance work.
• What the risk is: brief service interruptions are possible during the window. No extended outage is expected.
• What to do: if your business relies on Optus services during evening hours, plan around this window and check Optus's status page closer to the date for area-specific detail.

We recommend treating this as routine maintenance, but flagging it to any staff working late on 9 September.
