- A widespread technology outage has disrupted online banking, ACH payments, and services like Zelle for dozens of banks across the U.S.
- Customers have reported being unable to access accounts, missing direct deposits, and inability to transfer funds or use online bill pay.
- The outage raises broader concerns about the risks of dependence on third-party technology providers for core banking operations across multiple banks.
A major outage at financial technology provider Fiserv has left customers of dozens of banks and credit unions unable to access basic online banking services, including checking account balances, sending payments through Zelle, and receiving direct deposits.
Fiserv, one of the largest backend service providers in the U.S. financial system, with 10,000 customers, began experiencing issues early Friday morning, with problems escalating by 7 a.m. ET.
The outage has affected everything from mobile app functionality to ACH processing, online bill payments, and money transfers.
Banking Grinds To A Halt
Fiserv supplies the infrastructure behind many major financial institutions’ digital platforms. When its systems fail, the effects cascade quickly across the financial ecosystem.
Banks affected include major players such as Ally, Bank of America, TD Bank, Capital One, Synchrony, and Citizens Bank, as well as regional and local institutions like Northwest Bank, Sunflower Bank, and Farmers National Bank in Ohio. Credit unions such as Navy Federal. Even money transfer service Zelle appears to be impacted.
Customers have reported a range of issues: locked accounts, unavailable balances, non-functioning transfers, and missed direct deposits.
One IT staffer at a bank impacted by the outage shared on Reddit, “It’s been a nightmare. ACH files, Zelle, BillPay, and more have all been impacted.”

What Went Wrong
Fiserv has not confirmed what the cause of the incident is. According to reports, the outage allegedly appears to have originated from problems with its core processing software (DNA) and related services like Nautilus (document and content management) and Payment Exchange (real-time transfers).
While some functionality has returned for select services, many banks are still experiencing intermittent issues as of Friday afternoon.
We reached out to Finserv for comment but as of publication had not heard back. As of now, Fiserv has not released a public timeline for full restoration or details of the cause of the incident.
When The Back Office Becomes The Front Page
This incident is more than just an inconvenience – it highlights how fragile the digital banking experience can be when so many institutions rely on a single vendor.
Fiserv supports everything from transaction processing to statement delivery. When one system fails, it’s not just a front-end website that goes dark. Payments don’t go through. Payroll deposits don’t arrive. Consumers lose access to their money.
Farmers National Bank customers in Ohio reported not receiving paychecks because their employer’s payroll service was affected. “None of the employees at his work got their checks deposited either,” one customer wrote online.
What Customers Can Do
Right now, options are limited, but it appears many of the larger banks have started resorting services to customers. As of publication, we checked several of the larger impacted banks (Capital One and Navy Federal) and were able to access most online services. However, many are still showing banners, like the following at Farmers National Bank:
In the meantime, customers should:
- Check with their bank for updates on restoration times.
- Monitor social media or service status pages for real-time news.
- Keep documentation of any fees or financial consequences caused by the outage to request reimbursement later.
- Avoid retrying failed transactions repeatedly, which may result in duplicate charges once systems come back online.
If direct deposits or payments are delayed, employers and billers should be contacted. Many banks will work with customers on overdrafts or late payments caused by the disruption.
The outage raises urgent questions about redundancy and risk management across the financial sector. In an age when digital access to money is expected around the clock, the banking industry is facing a reckoning: how much operational control is too much to give away?
Regulators and consumer watchdogs may take a closer look at core banking vendors after this incident. For everyday banking customers, this serves as a reminder that while digital tools offer convenience, they also carry exposure to centralized points of failure.
