Six months after the EVA, spacesuit engineers still didn’t know the exact cause of the leak, although they quickly discovered which part failed—a fan pump separator that has since been replaced

I was a little disappointed at the lack of explanation about how the leak occurred. I hope they've figured out the details by now. It'd be interesting to know.

To me, the most interesting failure was the Hubble one. All because an engineer was confident that an observed error was a fluke due to gravity.
