The consultants said the Deepwater Horizon's blind shear ram was vulnerable to "single-point failure."

Still, the study said, blowout preventers remain vulnerable to the same "single-point failures."

It's the classic single-point failure with no back-up.

As in the conventional star network, individual nodes may thus still be isolated from the network by a single-point failure of a transmission path to the node.

They are self-healing systems designed with redundant components and automatic reconfiguration in the event of a component failure, to prevent against "single-point failures" (see Reliability engineering).

Over 80% of operational aircraft losses were traced to single-point failures of the electronics.

Requiring two shear rams in every blowout preventer may help to avoid this problem and to avoid some types of "single-point failure".

Step offices were more susceptible to single-point failures than newer technologies.

These were modular in a new way that was safe from all "single-point failures", yet would be only marginally more expensive than conventional non-fault-tolerant systems.

Hank was exaggerating; a single-point failure wouldn't snap the Line.
