Software upgrade not the root cause of Optus outage - Singtel

Optus had a 12-hour outage on 8 November.

Singtel dismissed reports that the upgrade conducted by Singtel Internet Exchange (STiX) was the root cause of Optus' massive network outage on 8 November.

STiX is one of Optus’ international networks that connects to the global internet.

On 8 November, STiX planned a routine software upgrade on one of its routers at 1 am SGT.

During the upgrade, data traffic was routed to other points of presence on the STiX network, and back into customers’ networks.

The STiX completed the upgrade within 20 minutes, and all its customers’ routers connected to it, including Optus’, were up and running.

"We are aware that Optus experienced a network outage after the upgrade when a significant increase in addresses being propagated through their network triggered preset failsafes. However, the upgrade was not the root cause," Singtel said.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
