Editor’s Note: this post was penned offline early Friday evening, before the author had knowledge of the issue being resolved, and fiserv processing the backlog as of 16:45. We have chosen to simply add some links, now that we are online to retrieve them. The post follows.
As I write, on Friday, 2025-05-02, fiserv has been offline all day, or substantially all day. This company acts as a third party to a number of banks, providing wire transfers, ACH, and/or direct deposit services, and possibly even online/mobile banking. A number of large banks, including Ally Bank, Bank of America, Capital One, and Synchrony have been affected in some way by this outage, as was my regional bank.
I don’t know anything about the root causes yet. It would be irresponsible to speculate about those causes, so of course I am going to.
