On Sunday 4 October 2026, the delivery of AEMO market data files was interrupted at the source during two periods:

• 7:50 pm – 8:37 pm AEST: no new data was received from about 7:55 pm. Delivery resumed at 8:37 pm, and all delayed data was loaded by 8:46 pm.
• 10:00 pm – 10:55 pm AEST: delivery was intermittent, and some data arrived up to 50 minutes late.

During these periods, ez2view, deSide and other services may have shown stale data or “Files are out of date” warnings.

The interruption originated in AEMO’s file delivery systems, upstream of Global-Roam. The same delay was visible in AEMO’s public NEMweb market data files, and it is likely to have affected many NEM participants. AEMO’s systems recovered on their own, and no action was needed on our side.

Customers don’t need to do anything, and restarting collectors won’t speed up recovery in this situation. All delayed data was loaded automatically once delivery resumed.

Dispatch and forecast data across all products appears to of being arriving slightly later than expected over the last 24hours: 13th July - 8am & 10am 14th July - 1am till 4am & 10am till 10:15

We will update this status page if more information becomes available on the cause of the delays, but data appears to be arriving on time now.

Dispatch and forecast data across all products appears to of being arriving slightly later than expected between the 30th June ~5pm and had settled again around the 1st July ~6pm.

We will update this status page if more information becomes available on the cause of the delays.

The generation of the bid file resources for ‘next day public’ bid data for both Energy and FCAS bids in ez2View was delayed this morning, due to an apparent data gap in AEMO dispatch data for a single unit (WKIEWA2) overnight.

Customers using ez2View likely experienced issues accessing up-to-date bid data in ez2View.

We will continue to monitor the situation, particularly for tomorrow’s bids, and if AEMO update the dispatch data we will also update the missing data.

Since 14:36 on Sunday 10 May 2026, the Constraints Plain English widget in ez2View has been unable to retrieve data. The widget relies on an upstream AEMO web service to translate constraint equations into plain English descriptions, and that service is currently returning errors.

We have confirmed the issue is on AEMO’s side and have raised a support ticket with them. We will update this post once we have more information or the issue is resolved.

Resolved 09:36 Tuesday 12 May 2026 - The widget resumed normal operation at 09:36 this morning.
