UPI outage caused due to certain banks, says NPCI as it plans fixes

Following three significant disruptions to the UPI system in recent days, the National Payments Corporation of India (NPCI), which oversees UPI transactions, has attributed the problem to certain banks. In a communication to partner banks, NPCI explained that on April 12, UPI experienced an unprecedented surge in requests from some banks excessively utilising the "Check Transaction" application programming interface (API). This surge led to a temporary slowdown in the system and significantly reduced payment success rates for several hours. According to NPCI, success rates plummeted to around 50 percent for two hours and hovered near 80 percent for the subsequent three hours between 11:40 am and 4:40 pm on that day.
