Critical payment processor failure
Third-party failure · Severe but plausible · 3 affected service(s)
SwiftLine Payment Networks suffers a software-defined-network failure across its primary and secondary regions at 09:40 on a business day. Wire and ACH connectivity drop mid-window with in-flight traffic in indeterminate states. SwiftLine's status page commits to 'restoration within hours' but its last comparable incident ran 7 hours. The bank's direct Fedwire contingency line was decommissioned in 2024; there is no alternate route.
