As amazing as it sounds that they couldn't see the connection between a thunderstorm and a system crash...those software guys simply could not think outside of the box. They were so busy defending the performance of the system that they couldn't see the obvious. Sometimes people get tunnel vision and need someone from the outside to point things out.
You're telling me that for 3 months nobody noticed that the system "occaisionally crashed" only during a thunderstorm? And nobody noticed a link between "thunderstorm" and "electrical interference" ? There are only two possible explanations for this:
1) Your software guys were pure software, with no knowledge of hardware (not credible) or
2) that your installation (like the PDP-11/VAX computer rooms I worked in when I wore a uniform) were situated underground.
