Telstra announced it has expanded its “Always On” service to provide more bandwidth options and lower latency on some of Asia’s busiest subsea cable routes – Hong Kong to Singapore and Japan to Hong Kong.

The service utilizes the scale and diversity of Telstra’s cable network in the Asia-Pacific region to reroute traffic to another path in the event of a cable cut or damage due to a natural disaster.

When Telstra launched its ‘Always On’ service guarantee last year, the service was targeted at customers with large capacity requirements of between 10GB and 1TB. The service has now been expanded to include lower bandwidth options starting at 1GB with the flexibility for customers to scale up as needed, said Paul Abfalter, director of international at Telstra.

“This enhancement, combined with our ultra-low latency connectivity across these key routes will be particularly beneficial for organizations in the financial services industry, where speed and reliability between global financial hubs are vital,” Abfalter said.

Abfalter added that Telstra now has “average speeds of 28.8 Mbps between the Singapore (SGX) and Hong Kong (HKEX) Exchanges, 177.8 Mbps between the Australian (ASX) and Chicago (CME) Exchanges, 178.2 Mbps between Equinix/CERMAK (EQCH) in Chicago and the ASX, and 41.9 Mbps and 13.9 Mbps respectively between Singapore to Taiwan and Hong Kong to Taiwan.”

Abfalter said Telstra’s Asia-Pacific subsea cable network accounts for up to 30% of active intra-regional capacity, which enables it to reroute traffic impacted by a cable cut onto another path to minimize downtime – an important capability in the Asia Pacific region where more than any other region globally, cables are at risk of service disruptions due to cable cuts caused by shipping activity, earthquakes and typhoons.

“Damage from these events can take weeks or sometimes months to fix,” he said.

Customers benefit not only from reducing that downtime to hours, but also from “cost savings associated with managing multiple vendors and paying for spare capacity that may not be used, while the assured availability helps improve the experience they provide their end users,” said Abfalter.
