The article frustratingly doesn't say whether this is a simple and correctable RAM one-bit error, or a permanent defect in a storage device. It's possible they don't know yet, but ideally, the A computer can be brought back to full functionality and serve as a backup to computer B.
The real irony will be if the defect was created by a stray neutron originating in its own radioisotope power supply.
