「The Company has been proceeding with a relocation plan that includes selecting a disaster-resilient data center and a vendor with expertise in payment systems and virtualization technology, conducting a third-party evaluation of the architecture, including the migration method, and ensuring sufficient time for changeover work and operational checks through the early construction of the new data center, as well as developing a backup plan.」
Although the dependency risk remains, countermeasures have progressed, including the selection of the relocation site and vendor, a third-party evaluation, a backup plan and the decision on when to close the existing center. - FY2023First statedAnnual report
「Because the Company relies on a specific data center, if use of its facilities or network were to be disrupted by a fire, earthquake or other natural disaster, a large-scale external communications failure, external damage, a system failure caused by human error, or any other unforeseen event, it could be forced to suspend its services.」
The Company cites multiple servers, backups, access-log reviews, recovery drills and a relocation plan for 2025 as countermeasures.
