This is probably the most bizarre issue I’ve had in my career in IT. One of our multi-practice facilities is having a new MRI installed and apparently something went wrong when testing the new machine. We received a call near the end of the day from the campus stating that none of their cell phones worked after testing the new MRI. My immediate thought was that the MRI must have emitted some sort of EMP, in which case we could be in a lot of trouble.

After going out there we discovered that this issue only impacted iOS devices. iPads, iPhones, and Apple Watches were all completely disabled (or destroyed?).

GE claims that the helium is what impacts the iOS devices which makes absolutely no sense to me. I know liquid helium is used as a coolant for the super-conducting magnets, but why would it only effect Apple devices?

What a crazy story. Be sure to check out one of the follow up posts.
