An hour later the company posted about the problem again, but offered no timetable on when it would be fixed.
The Lake Johanna Fire Department confirmed an activation of the fire suppression system at the Wells Fargo facility in Shoreview, Minnesota due to construction dust, not a fire.
The same day, Wells Fargo tweeted that their technical team had resolved the issue; however, customers are still allegedly without access to the mobile banking app and desktop site.
Outraged customers reported they could not access their accounts on the Wells Fargo app or website, use ATMs, or even make purchases with their debit cards. "We apologize for the inconvenience", Wells Fargo told Newsweek.
Starting around 6am Pacific Time (2pm UTC), the American bank's online portal and its mobile application have been totally unusable. The bank apologized on Friday for a similar outage.
Wells "probably doesn't want to get their stuff back up now because they know a ton of people will be switching banks as soon as they do", Mimsy added on Twitter.
A customer service representative reportedly said it is a nationwide outage.
Wells Fargo did not immediately respond to FOX Business' request for additional details.
