TD Bank’s system is operating again after experiencing widespread system outages this morning that it attributed to a technical issue.

“We identified the issue and worked quickly to resolve it. We apologize for any disruption,” bank spokesman Matthew Doherty said, without revealing more details about the nature of the problem.

Customers were not able to get into their bank accounts online or at ATMs or use their debit cards, according to social media posts by customers and responses by the bank. The website Down Detector shows the problems began to be reported during the night and escalated around 6 a.m.

An employee at a Portland branch said all branches of TD Bank were down. The bank, which is a subsidiary of Canadian multinational Toronto-Dominion Bank, has 44 branches in 35 Maine towns. The bank said earlier this month would close three Maine branches as part of a 15-state streamlining effort.

On Twitter, the bank said “due to an unforeseen technical issue, customers and employees are currently unable to access account information in person, online or by phone. We are working on this and hope to have it fixed within an hour or two.”
