In a letter to nearly 1,000 patients, University Hospitals in Ohio says that a tank's remote alarm system, meant to alert an employee to temperature swings, was disabled for an unknown length of time. That led to the destruction of around 4,000 frozen eggs and embryos, double the original estimate:
Hospital officials say they doesn't know who turned the remote alarm off or how long it was disabled. They also said they were aware the tank in question needed preventative maintenance. Some of the eggs and embryos had been stored there since the 1980s. The hospital's investigation is ongoing.
"Right now we do not know whether it's mechanical or human or [a] combination," said James Liu, chairman of the department of obstetrics and gynecology at University Hospitals.
He says he doesn't think anyone intentionally disengaged the alarm. "Because it is a computer, we think it's unlikely that there was any kind of external force that was working to hack the computer or anything like that. We think it's unlikely," Liu said.

With the transistors getting smaller, I think is reasonable a cosmic ray incident will cause more extensive damage by flipping more transistors. The frequency may stay the same, just the damage is more intensive.
Now, I don't know how much of that study looked into the isotopic composition of the materials around. E.g the chips are covered in plastic and 14C (in 1 ppm abundance) is radioactive. 40K - potassium - will be present in the concrete that makes the building - half chances to decay in energetic gammas that penetrate the chips.
