There was a major outage this afternoon which took many Sydney digital radio services off air in prime time for about an hour.
Various commercial and community radio services are known to have been affected by the failure, which began just after 5pm.
The issue was traced back to Telstra, which had a major equipment failure inside the North Sydney exchange.
Transmissions from the Artarmon site went to air, but program was appearently not able to reach the transmission site.
The fault affected many Telstra customers’ phone and internet services, as well as knocking out the feeds from studios to the digital radio transmission tower.
Telstra remotely reset its equipment and stations were reported to be back on air some time after 6pm.
