There was a widespread outage of Unified Payments Interface (UPI) services on Monday, leading to nationwide transaction failures affecting millions of SBI, Google Pay, and Paytm users across India. The outage, which led to disruption in fund transfers, payments, and app operations, peaked in users' complaints during the afternoon and evening. Subsequently, the National Payments Corporation of India (NPCI), operating UPI, acknowledged that the outage was a result of random technical issues but had ensured the restoration of the system.
