Optus outage update: Telco reveals cause of network failure - 9News

The telco, which admitted it took longer than it would have liked to investigate the cause, said routers disconnected from its core network after the maintenance.

"At around 4.05am Wednesday morning, the Optus network received changes to routing information from an international peering network following a routine software upgrade," an Optus spokesperson said.

"These routing information changes propagated through multiple layers in our network and exceeded preset safety levels on key routers which could not handle these.

"This resulted in those routers disconnecting from the Optus IP Core network to protect themselves."

The spokesperson said some of the routers had to be manually reset, which is why it took so long to fix the 13-hour outage.

"The restoration required a large-scale effort of the team and in some cases required Optus to reconnect or reboot routers physically, requiring the dispatch of people across a number of sites in Australia," the spokesperson said.

"This is why restoration was progressive over the afternoon.

"Given the widespread impact of the outage, investigations into the issue took longer than we would have liked as we examined several different paths to restoration.

"The restoration of the network was at all times our priority and we subsequently established the cause working together with our partners.

"We have made changes to the network to address this issue so that it cannot occur again."

The outage on Wednesday left many of Optus' roughly 10 million customers without internet and phone connectivity, and impacted their ability to contact emergency services.

The government has announced an inquiry into the outage, which Optus said it will cooperate with.

"We are committed to learning from what has occurred and continuing to work with our international vendors and partners to increase the resilience of our network," the spokesperson said.

"We will also support and will fully cooperate with the reviews being undertaken by the government and the Senate."
