Rule #1, don't trust the telco or the power company, or anyone else feeding
wires into your building to do a good job keeping you safe from surges.
A client of mine has what used to be a CSU/DSU... now has surface mount
components missing and the like. They hadn't installed a surge protector on
the T-1. They had covered the power and the antenna coaxes at the site.
Only the T-1 line was unprotected. Lightning will find that one path you've
not protected.
The cost of installing a surge protector is unlikely to impact your bottom
line. One successful lightning strike on the other hand will hurt quite a
bit, and probably happen at 4AM just to be more annoying.
