UPI Servers Restored After Brief Outage.
"UPI is operational now, and we are monitoring the system closely," the National Payments Corporation of India (NPCI) said.
Intermittent technical glitch: National Payments Corporation of India

The NPCI is a tweet that acknowledged the technical glitch and said that UPI is operational now. However, some of the users continued to face issues.
ICICI Bank has reportedly notified that its UPI system is down due to maintenance activities.
"Regret the inconvenience to #UPI users due to intermittent technical glitch. #UPI is operational now, and we are monitoring the system closely. (sic)," it said.
The food delivery apps such as Zomato and Swiggy also showed high incidences of payment gateway errors on Friday late afternoon, prompting users to perform transactions by credit/debit card.
“Yes, ICICI Bank has notified that its UPI system is down because of maintenance activities. Not sure about other apps though. Didn't know they work on Sundays too but doing such activities actually makes sense on weekends though.”
Several users had taken to Twitter to report that the UPI server was down and they were not being able to make any transactions using digital wallets and online payment platforms such as Google Pay and Paytm.
However, some of the users complained of facing issues even after this. Check out some of the tweets on the issue:
Late on Sunday evening, the National Payments Corporation of India, the umbrella organization for all retail payments systems in India, said that this was an ‘intermittent technical glitch’ and that UPI is now functional after an initial glitch. According to NPCI, the services get restored after 6 pm.
Several users wondered if there is really some problem with UPI or it was just a problem on their end.
According to recently released data, in December 2021, UPI recorded 456 crore transactions valuing the total amount at Rs. 8.26 Lakh Cr (approx. $111.2 billion).
Furthermore, UPI transactions registered dealings worth more than Rs. 73 Lakh Cr (approx. $970 billion) from January 2021 to December 2021. There is a year-on-year increase of over 110% compared to the calendar year 2020.
Google Pay through their official Twitter account responded by asking him the particular issues he is facing so they can fix them.
However, Google Pay reminds users not to reveal any private information on social media when reporting their problems.
