I call lightning damage and suggest suppression devices on both ends of the cable at this location. Sites that have continuous problems help identify when something isn't right ground-wise with the install. Every time lightning comes close the problem will repeat itself most likely. Your installation might be the same but maybe they added a ground rod somewhere that is affecting your install, maybe they lost some grounding - maybe similar at another close building etc.. Can't really tell you can just start to make changes until you have no more problems. That's my guess. Seen the same thing here at a couple of sites.
