Service NSW app restored after outage

The Service NSW app has been restored after it suffered an outage this afternoon, leaving residents unable to check-in to venues across the state.

Service NSW said QR code check-ins and the Dine and Discover vouchers were impacted around 4pm this afternoon.

"We're working to resolve this ASAP and apologise for any inconvenience," Service NSW said on Twitter.

The application plays a vital role in the state's 'gold star' contact tracing system.

By 6pm, the app and all of its services were back online and working again.

A technical outage is being blamed for the temporary outage.
