Why will SBI UPI services go offline for 45 minutes on October 3?

The UPI services provided by SBI will go offline for 45 minutes on October 3 due to scheduled maintenance work. The work will begin at 12:15 am (00:15 hrs) and continue until 1:00 am (01:00 hrs). "The activity may, however, be completed early. Customers may continue to use UPI Lite services for uninterrupted service," SBI said.
