The Federal Reserve confirmed that part of its National Information Center, or NIC, system was disrupted on August 5, temporarily affecting the system's public website while key functions remained operational. According to Sina Finance, the outage also affected internal systems, and an internal email said key data pipeline tasks from the NIC kept failing and caused significant downstream impacts across multiple Fed business areas.

The email said one affected area was the Fed's discount window, the main channel through which the central bank lends directly to banks. The NIC is managed by the Federal Reserve, and the Federal Deposit Insurance Corporation and the Office of the Comptroller of the Currency also rely on the system.

Senator Elizabeth Warren wrote to Michelle Bowman, the Fed's vice chair for supervision, on September 11, saying the outage raised concerns that staffing cuts had disrupted maintenance of the NIC system. In another letter to the top supervisory officials at the Federal Deposit Insurance Corporation and the Office of the Comptroller of the Currency, Warren said reductions in bank examiner positions at federal regulators raised concerns about their ability to identify and respond to emerging risks.
