Our upstream provider has advised that the fault has been isolated to two devices within Optus' network. A workaround has been put in place and emergency maintenance has been completed on the first of these two as scheduled yesterday. We are advised that all calls are now flowing correctly and there should be no further impact as a result of this fault.
Further maintenance is scheduled for this evening at 23:00AEST on the second device to fully resolve the fault condition and restore full capacity and redundancy.
