False fire alarm leads to outage affecting BMO mobile app, online banking

The Bank of Montreal (BMO) is working to restore service to its online banking and mobile app, which was affected by a false fire alarm overnight at one of its data centres.

Users began reporting issues with the app and website several hours ago, with a BMO spokesperson responding to social media accounts on X, formerly known as Twitter, on Thursday.

“Heads up: You may not be able to access online banking right now because of a technical problem,” they wrote on X. “We’re working on the issue and will get things back to normal as soon as we can. Thanks for your patience.”

A BMO spokesperson tells CityNews that the service disruption was caused by someone pulling a fire alarm at one of the bank’s data centres.

On the BMO website, there is a notice that says, “You may not be able to access online banking right now because of a technical problem.”

“We’re working on the issue and will get things back to normal as soon as we can.”

It’s unclear when service will be restored online and through the mobile app. In the meantime, BMO said customers can get updates and continue to access their accounts through BMO’s ATM network.
