Many HDFC Bank Ltd customers could not access their account information through the net banking and mobile banking portals for the second day on Tuesday due to a technical glitch.

“We apologise that the resolution of the technical glitch is taking more time than anticipated. Our experts are working round the clock. While some customers are able to transact using netbanking and mobilebanking app, a few may still be facing intermittent issues," HDFC Bank tweeted on Tuesday.

The services have remained unavailable since 10am on Monday. Incidentally, the bank had faced a similar outage last November when it had launched a new version of the mobile banking app.

Since Monday morning, customers trying to log into the mobile app or net banking portal received a standard response: “Dear user, the netbanking system is busy processing heavy load from currently logged in customers, request to try after some time. Thank you for your cooperation." Thousands of irate customers took to Twitter to express their displeasure. HDFC Bank has 45 million customers and at least half of them use its digital channels. Shares of the lender closed 0.77% lower at 1,255.65 on BSE. They had closed 0.7% down on Monday. The BSE Sensex remained almost flat at 40,675.45.
