We will be undergoing scheduled maintenance of the Open Data Hub today (20/12) between 12:00 and 14:00. During this time the Open Data Hub (https://opendata.transport.nsw.gov.au) will be unavailable. However, the Developer Portal (https://developer.transport.nsw.gov.au) will be unaffected and can be used.
If you have any questions please post them in this thread.
