MUFG Bank and NTT DATA have successfully tested a cutting-edge solution to minimize IT outages by migrating live banking systems between data centers with less than one second of downtime.

Using the IOWN All-Photonics Network (APN), the first test involved transferring a virtualized financial system across multiple data centers within a 70 km radius. Key performance indicators, such as data transfer time and system availability, demonstrated the technology’s effectiveness, offering a near-seamless migration experience without the typical disruptions caused by planned maintenance windows.

A second test assessed database synchronization across distances ranging from 250 to 2,500 km, showing significant improvements in reducing synchronization delays and fluctuations. The ability to maintain near-instantaneous data replication over long distances could revolutionize how financial institutions handle system transfers, even during peak business hours. Tom Winstanley, CTO at NTT DATA UK&I, emphasized the importance of such advancements, noting that the financial industry’s evolution demands infrastructure capable of meeting growing global needs.

The urgency for such innovations comes as MUFG has recently faced multiple IT outages, including suspected Denial-of-Service attacks in December and January. In addition, the bank was fined over $1.75 million for deficiencies in its information management and monitoring systems. By leveraging IOWN’s photon-based communication network, MUFG aims to enhance resilience and prevent future service disruptions that can result in financial penalties and reputational damage.
