In November 2016, Cisco discovered a critical failure with the clock signal component manufactured by a third-party supplier. This critical failure will cause devices to stop passing traffic after approximately 18 months in service. The failure will manifest similar to a Denial of Service attack.
According to Cisco, "once the component has failed, the system will stop functioning, will not boot, and is not recoverable." Given this, it's critical that you stay ahead of the component failure by replacing any devices in production before the 18 month window has arrived.
While this failure isn't specific to Cisco-branded equipment, it is the only manufacturer who has publicly identified the problematic components exist in their equipment. As new manufacturers release their included product lists, we will update this page in a timely fashion. To be alerted of new devices discovered, fill out the form below.
