What Happened
The problems began shortly after 5:00 a.m. ET, when customers across several states noticed that their direct deposits were missing or delayed. At the same time, many were locked out of the mobile app or faced error messages when attempting to use the bank’s website.
By mid-morning, outage trackers showed thousands of reports, making it one of the largest digital disruptions M&T Bank customers have faced this year. For many, the timing was particularly difficult—Friday morning is payday for millions of workers who depend on direct deposit to pay bills, rent, and other essentials.
Services Impacted
The disruptions were widespread and hit several core services:
- Mobile App Access: Customers reported blank screens, error messages, or repeated login failures.
- Online Banking Login: Even those trying to bypass the mobile app through the website experienced lockouts or slow loading times.
- Direct Deposit Delays: Many customers could not see their paycheck or recurring deposits reflected in their balances.
- Account Balance Errors: Transactions and balances were slow to update, leaving customers unsure of their available funds.
States Affected
M&T Bank operates heavily along the East Coast, and the impact was felt in multiple states including New York, Maryland, Connecticut, Pennsylvania, and Washington, D.C. Customers in these regions were among the first to raise concerns, though scattered reports came in from across the bank’s broader footprint.
How the Bank Responded
M&T Bank acknowledged the online banking issues by late morning, confirming that both mobile and online platforms were experiencing “intermittent problems.” Technology teams were immediately assigned to investigate and restore functionality.
By the afternoon, partial access returned for some customers, though direct deposit delays lingered. It wasn’t until early evening, around 6:30 p.m. ET, that the bank declared the issues resolved. Officials apologized for the inconvenience and reassured customers that monitoring would continue through the weekend to ensure stability.
Customer Experience
The frustration among customers was clear. Many reported that:
- Paychecks expected in the morning did not show up until later in the day.
- Bill payments scheduled through online banking failed to process on time.
- Those relying solely on the mobile app had no alternative way to check their balances.
- Some faced anxiety about overdraft fees or late payment charges caused by missing funds.
For individuals and small businesses that depend on consistent cash flow, the outage created serious challenges.
Timeline of Events
5:00 a.m. ET: Early reports surface of missing direct deposits and app errors.
8:00 a.m. ET: Complaints spike as login failures spread widely.
10:00 a.m. ET – 2:00 p.m. ET: Outage reports peak, topping 2,000 within hours.

Past Disruptions
This is not the first time M&T customers have faced online banking issues. Over the past few years, the bank has struggled with system upgrades and integration challenges. In particular, customers have voiced concerns about outages following large-scale technology transitions.
The latest disruption adds to a pattern of frustrations, prompting questions about whether the bank’s digital infrastructure is keeping up with modern demands.
Why This Matters
In today’s economy, most customers rely heavily on digital access to their money. An outage like this doesn’t just cause inconvenience—it can create real financial stress. Consider the ripple effects:
- Employees waiting for paychecks to pay bills.
- Renters needing direct deposits to clear on time.
- Families left uncertain about whether funds were actually available.
- Businesses unable to process payments or payroll.
Bank reliability is about more than convenience. It’s about trust. Every time a large financial institution suffers digital problems, customer confidence is shaken.
What Customers Can Do
If you were affected by the outage, there are steps worth taking:
- Check Your Account Again: Log back in to confirm that deposits have arrived and balances are correct.
- Monitor Transactions: Ensure that no scheduled payments were missed or duplicated.
- Contact Customer Service: If you incurred overdraft fees or late payment penalties due to the outage, request reimbursement.
- Set Up Backups: Consider enabling alerts for deposits and balances to spot delays faster in the future.
Lessons for the Banking Industry
The M&T Bank online banking issues highlight broader questions facing the U.S. banking sector. As more customers move to digital-first banking, institutions must invest heavily in system reliability. Outages are no longer just an inconvenience; they risk customer loyalty, regulatory scrutiny, and reputational damage.
Key improvements banks may need include:
- Stronger redundancy systems to prevent total lockouts.
- More transparent communication during outages.
- Faster resolution times to minimize disruption.
- Greater investment in modernizing legacy systems.
The Road Ahead for M&T Bank
For M&T Bank, this outage comes at a sensitive time. The company has been working to strengthen its customer service network and rebuild trust after previous disruptions. While the September 19 outage was resolved in under a day, the memory of missed deposits and login failures will linger with customers.
How the bank communicates moving forward—and whether it can prevent future outages—will determine how much trust is regained.
Final Thoughts
The M&T Bank online banking issues of September 19 showed just how disruptive a digital outage can be for everyday customers. From missing paychecks to login failures, thousands of people were affected across the East Coast and beyond. Although service was eventually restored, the incident underscores the growing importance of reliability in online banking.
